Ivy Lee Method for Remote Work: 6-Task Evening Plan

When the Office Disappears, What Tells You What to Work On Next?

By ten in the morning you have already made the same decision a dozen times: what do I do next. There is no commute to start the day, no manager walking past the desk, no shared office rhythm to lean on, just an open laptop and a wall of choices that resets every hour.

The Ivy Lee Method answers that with a single decided sequence. Each evening you write down the six most important tasks for tomorrow, rank them by importance, and work through them one at a time without skipping ahead. For remote workers it does a specific job: it rebuilds the structure the office used to supply, folded into a list you set the night before. The constraint is simple enough to fit on a single index card, and for anyone drowning in open tabs and message pings, that hundred-year-old limit is more useful now than ever.

What You Will Learn

• Where the Ivy Lee Method came from and why a hundred-year-old rule still holds up.
• Why the six-task limit forces better prioritization than an open to-do list.
• The five-step evening routine that sets tomorrow before you close your laptop.
• The three adaptations that rebuild the structure remote work removes.
• How the method compares to other daily systems, and when to reach for something else.

Key Takeaways

• The Ivy Lee Method caps daily focus at six ranked tasks worked one at a time [2].
• Writing tomorrow’s to-do list before bed helped participants fall asleep roughly nine minutes faster in Scullin and colleagues’ small sleep-laboratory study of young adults [3].
• The Six-Task Ceiling Effect, our name for the constraint at the heart of this method, forces prioritization by limiting your daily commitments.
• Task switching carries measurable cognitive costs even when switches are predictable, including slower responses and more errors, as Stephen Monsell documented in his review of task-switching research [4].
• End-of-day reflection improved performance in one Harvard Business School working paper (field and lab studies); treat the effect as directional, not precise, since the paper is not yet peer-reviewed [5].
• Evening planning replaces the commute, the walk-past-your-desk boss, and the office rhythm that remote workers lose.
• Unfinished work tends to linger in the mind, the Zeigarnik effect, and across a work week that lingering has been linked to poorer weekend sleep through rumination [6].
• Rolling unfinished items forward keeps the system honest without creating guilt.
• The Ivy Lee Method is one of several daily planning methods that work, and it suits people who want a strict, single-sequence routine.

Where Did the Ivy Lee Method Come From?

The Ivy Lee Method traces back to a story set at Bethlehem Steel Corporation in 1918. At the time, Charles Schwab ran what was then the largest shipbuilder and second-largest steel producer in the United States. The popular version, retold by productivity writer James Clear [2], says Schwab brought in consultant Ivy Ledbetter Lee and asked him how to get more done. Lee then spent fifteen minutes with each executive giving identical instructions: write six tasks each evening, rank them, and work through them in order the next day.

It is worth being honest about the evidence here. The story circulates widely in productivity writing but lacks a verified primary source. So the specific figures below, the per-executive time, the trial length, and the check amount, are best read as the popular account rather than documented fact. What survives scrutiny is the method itself, which maps cleanly onto modern research on attention and planning.

The Ivy Lee productivity system has survived for over a century because simplicity applied consistently tends to outperform complexity applied sporadically. Crediting one technique for a steel empire’s success would be a stretch, and the dollar figures belong to the legend rather than the ledger. The underlying principle is what holds up: fewer decisions, better execution.

Those principles translate directly into the five-step evening process below.

Why Does the Six-Task Limit Change Everything?

The six-task limit changes everything because it moves the hard part of your day, deciding what matters, out of execution and into planning. The Six-Task Ceiling Effect is our name for that shift, the productivity advantage that emerges when a fixed, small cap forces prioritization into the planning stage instead of leaving it for execution. Most productivity systems tell you to capture every task, tag it, and sort it into categories. The Ivy Lee Method takes the opposite approach: it asks you to commit to just six things, and that ceiling is doing real cognitive work.

When you know you can only choose six tasks, three things happen. First, you’re forced to cut. You can’t fit twelve things into six slots, so you confront what actually matters versus what merely feels urgent. Second, you reduce your decision load the following morning. Research on decision fatigue, while still debated in the literature, suggests that repeated choices can degrade the quality of later decisions throughout the day [7]. By pre-selecting your six tasks the evening before, you skip dozens of “what should I work on next?” micro-decisions. Third, you get a completion signal. An uncapped to-do list never feels finished, but a ceiling of six tasks makes completion genuinely possible.

Why six and not three or ten? The number sits in a well-studied range for how much we can hold in mind at once. George Miller’s classic 1956 work suggested short-term memory holds roughly seven items, plus or minus two [10], while Nelson Cowan’s more recent research in Current Directions in Psychological Science revised the active limit downward, arguing that working memory effectively holds closer to four chunks once rehearsal and chunking are controlled [8]. Six sits between those poles: enough to fill a productive day, few enough to stay close to what you can comfortably keep in your head.

The practical payoff shows up in how that small list protects your focus, since it pairs naturally with the kind of single-task concentration that Cal Newport popularized as deep work, shielding long stretches of attention from the pull of an open queue. That protection matters more in 2026 than it did in 1918, because modern knowledge work fragments into very short bursts. A 2025 workplace study by Talypova and colleagues, pointedly titled Are Six Minutes of Focus Enough?, set out to study these everyday multitasking patterns, and its framing captures the problem a remote worker faces: focused stretches are now measured in minutes, not hours [13]. A ranked sequence will not silence every interruption, but it gives you a decided next action to return to each time your attention scatters.

How Do You Apply the Ivy Lee Method? The 5-Step Evening Process

You apply the Ivy Lee Method by spending under ten minutes each evening on five steps: close out today, write six tasks for tomorrow, rank them, place the list where you will see it, and shut down. Each step is small, and the whole routine is short enough to survive a real week. Here is how it works.

Step 1: Close Out Your Current Day (2 Minutes)

Before you plan tomorrow, take stock of today. Mark off what you completed and note what stalled. In one Harvard Business School working paper that included both lab and field studies, Di Stefano, Gino, and colleagues tested this directly. The field component followed call-center trainees in an Indian outsourcing context: employees who spent fifteen minutes reflecting at the end of each training day performed better on a later test than those who spent the same time on extra practice. One honest caveat: the result comes from a working paper, not a peer-reviewed journal article. The exact percentage reported in secondary write-ups could not be independently verified, so treat the effect as a clear direction rather than a precise number [5].

Employees who spent fifteen minutes at the end of each day reflecting on lessons learned went on to perform meaningfully better than those who used the same time for additional practice. (Di Stefano et al., Harvard Business School Working Paper, not yet peer-reviewed; the precise effect size reported in secondary sources could not be independently verified [5])

You don’t need a journal entry. A quick mental audit is enough.

Step 2: Write Down Six Tasks for Tomorrow (3 Minutes)

Write the six most important things you need to accomplish tomorrow. Not six things you could do, six things that would make tomorrow a successful day. Include any rolled-over priorities from today. Phrase each task as a concrete action: “Draft the Q2 budget summary” beats “Work on budget.” And if you have fewer than six important tasks, don’t pad the list with busywork.

Size matters as much as wording. A good Ivy Lee task is small enough to finish inside a single work session and concrete enough to start without further planning. If an item is really a multi-day project, “launch the new pricing page,” for example, it does not belong on the list as one line. Put the next session-sized slice on the list instead (“write the three pricing tiers and their copy”), and let the rest of the project surface as future tasks on later evenings. The rule of thumb: if you cannot picture finishing it tomorrow, it is too big and needs to be split before it earns a slot.

Step 3: Rank Them by True Importance (2 Minutes)

Number your tasks one through six. Ask yourself: “If I could only finish one thing tomorrow, which one would make the biggest difference?” That’s your number one. This ranking sets your work order. You start with task one and don’t touch task two until it’s done. The Ivy Lee Method’s sequential constraint prevents the common trap of starting easy tasks to avoid hard ones.

Rank by importance, which is not the same as urgency. Importance is how much a task moves your own goals forward; urgency is how loudly a deadline is shouting, often on someone else’s behalf. When the two pull apart, rank by impact on your goals rather than by deadline pressure alone, and use a triage step like the Eisenhower Matrix first to strip out anything that is merely urgent before you build the list. Two cases come up often. First, an external deadline competing with self-directed strategic work: give the deadline an early slot only if missing it carries a real cost, otherwise protect the strategic task at number one while your focus is freshest, since it is the one nobody else will chase for you. Second, two tasks that feel equally important: break the tie by reversibility and reach, putting the one that is harder to undo or that unblocks other people ahead of the one you can redo or that affects only you. If you want the research behind why doing one thing at a time beats juggling, our guide to the benefits of single-tasking covers it in depth.

Step 4: Place the List Where You’ll See It (1 Minute)

Pin your list to your monitor, leave a card on your keyboard, or set your task app to display it on launch. The goal is zero friction between sitting down and starting task one. A plain printed card works as well as any app: rule six numbered lines on an index card, or copy the simple six-line Ivy Lee template below, which you can reuse each evening. The Goals and Progress workbook includes an evening planning worksheet built around exactly this ranked-task structure, so you have a fillable version if you prefer paper.

Step 5: Shut Down and Walk Away (1 Minute)

Once your list is set, close your laptop. Leave the workspace. As Scullin and colleagues reported in the Journal of Experimental Psychology: General, participants who wrote a specific to-do list before bed fell asleep nine minutes faster on average than those who wrote about completed tasks [3].

“The more specifically participants wrote their to-do list, the faster they subsequently fell asleep.” (Scullin et al., Journal of Experimental Psychology: General [3])

Writing tomorrow’s task list in the evening gets the open loops out of your head and onto paper, so they stop circling while you try to wind down. The instinct that unfinished work keeps tugging at attention has a name, the Zeigarnik effect, classically described as the tendency for incomplete tasks to stay more active in memory than finished ones. That memory-advantage claim is worth holding loosely, though. When Ghibellini and Meier pooled the experimental record in a 2025 meta-analysis, the part that held up was not the memory edge but a related pattern, the Ovsiankina effect: a general pull to resume tasks that were left unfinished [15]. So the honest version of the idea is less about better recall and more about an unfinished task quietly pressing to be picked back up, which is exactly the pressure that writing it down relieves. Studying employees over twelve weeks, Syrek and colleagues found that unfinished tasks at the end of the work week were linked to poorer weekend sleep, with rumination as the path between the two [6]. Their study looked at the weekly cycle rather than a single night, so read it as evidence that lingering tasks cost recovery, not as a measured result about one evening’s to-do list.

The Morning Side: How to Actually Start

The evening half of the method gets most of the attention, but the morning half is where it pays off, so it deserves its own routine. When you sit down to work, do not reopen your inbox or your chat app first. Read the list, look only at task one, and begin. Because you decided last night, there is nothing to triage and no “what should I do first” to negotiate. The on-ramp is already built.

Two morning situations come up often. First, what if task one is blocked, waiting on someone else, missing a file, or stalled by a dependency? Move it to a holding spot at the bottom of the list, note what unblocks it, and start task two. The sequential rule bends for genuine blockers; it does not bend for difficulty. Second, what if task one is unclear and you are not sure where to begin? That is usually a sign the task was written too vaguely the night before. Spend sixty seconds rewriting it as a concrete first action (“open the budget file and fill in the three known line items” rather than “do the budget”), then start. The point of the morning is to protect the decision you already made, not to re-litigate it.

One pattern is worth flagging because it took a while to notice in practice: the task that keeps getting picked as number one but never actually gets done. For a stretch of several weeks it was always the same kind of item, a piece of writing that needed a real block of thinking, parked at the top of the card every single evening and quietly skipped every morning in favor of task two. The list was technically working, since five of six tasks closed most days, but the one that mattered most never moved. The fix was not more discipline; it was admitting that a task surviving five untouched mornings is a sizing signal, not a willpower problem, and cutting it into a thirty-minute first slice that could actually be finished before the inbox opened. That single reframe, treating chronic rollover as data rather than guilt, is the part of the method that changed the most for me.

How Should Remote Workers Adapt the Ivy Lee Method?

Remote workers adapt the Ivy Lee Method by adding the structure an office used to supply: a fixed evening planning time, a calendar check for meeting load, and a set window for reactive work. The original method was designed for 1918 steel executives with clear start and end times, and remote work in 2026 looks nothing like that, nor is it a temporary arrangement. Barrero, Bloom, and Davis, tracking work-from-home patterns in the Journal of Economic Perspectives, found that remote and hybrid schedules had stabilized at a high level rather than reverting to pre-2020 norms [12]. Those figures reflect data through mid-2023, so read them as evidence that the shift settled rather than faded, not as a precise reading of the current year.

That stability is the practical case for building a real home-office planning habit instead of improvising one. A larger 2024 evidence base points the same way: in a meta-analysis of 108 studies covering more than 45,000 workers, Gajendran and colleagues found that remote work, on balance, raised job satisfaction, organizational commitment, and supervisor-rated performance, while also carrying real costs through a second pathway of isolation and reduced support [14]. The upside is real, in other words, but so is the structural gap a deliberate routine is meant to close.

Whether you work from home full-time or split the week in a hybrid schedule, these three adaptations close the gap the office used to fill. They are what turn the Ivy Lee Method into a real work-from-home productivity system.

Adaptation 1: Define a Hard Planning Boundary

Office workers leave the building and the workday ends. Remote workers don’t have that signal, and the cost of losing it is real. In a three-wave survey of Finnish workers during the pandemic period, Van Zoonen and Sivunen found that remote work and heavy reliance on mediated communication were associated with greater isolation and psychological distress, with the effect intensifying as in-person contact dropped [11]. That is one country in an unusual stretch of time, so treat it as a documented risk to guard against rather than a universal law, though the broader 2024 meta-analysis above points to the same isolation cost across a much wider sample [14]. A firm shutdown ritual is one practical guard against that drift. Pick a specific time each evening to write your six tasks and attach it to something you already do, a technique James Clear popularized as “habit stacking” in Atomic Habits [16]. For example: “After I close my laptop for the day, I write tomorrow’s six tasks before I leave my desk chair.” Your Ivy Lee list becomes the line between work and the rest of the evening. Whether you use a plain index card or a minimal app like Apple Notes or Google Keep, the tool matters less than the consistency. If your remote setup needs a fuller focus structure around this, our guide to deep work for remote workers goes deeper on protecting concentration at home.

The failure mode here is specific and worth naming, because it is the one that catches most home-office workers. You finish a call at 6 p.m., tell yourself you will plan tomorrow “after dinner,” and by 9 p.m. the day has dissolved into messages and half-watched television with no list written. The next morning starts cold, with twenty minutes of triage instead of task one. Anchoring the list to the laptop-closing moment, rather than to a fuzzy “later,” is what removes that gap, and it is the single change that most often turns a method that sounds good into one that actually holds.

Adaptation 2: Account for Meeting Blocks

Check your calendar before writing the list. On heavy meeting days, choose three or four deep-work tasks and reserve slots for meeting-related actions. On light days, load up with project work. Don’t treat meetings themselves as tasks unless they require specific preparation, since the list is for work you control. If your days are dense with calls, pairing the list with a calendar method helps; our guide to the time blocking method shows how to slot the six tasks around a meeting-heavy schedule.

Adaptation 3: Build a Collaboration Window

Block one to two hours daily for reactive, collaborative work: responding to messages, reviewing pull requests, handling requests. Outside that window, stay on your Ivy Lee list. This isn’t about ignoring your team, it’s about batching responsiveness so collaborative tasks don’t fracture your focused work.

A practical question follows: should all that reactive work appear on the six-item list? Mostly no. Keep individual replies, reviews, and pings off the ranked list and let the window absorb them, since listing them line by line would blow past six in an afternoon. The one exception is a collaborative item heavy enough to deserve real focus, a thorough design review or a written decision document, which earns its own ranked slot like any deep-work task. Everything lighter rides as a single entry such as “clear the collaboration window” rather than a dozen separate lines.

Here is the part that keeps the mental model coherent: the collaboration window is not an exception to the sequential rule, it is a standing background slot you planned in advance. You still finish task one before task two during focused hours. The window simply holds all the reactive work that would otherwise interrupt that sequence, and it runs at a fixed time rather than whenever a notification arrives. Let your team know your availability pattern so the window is predictable on their side too.

On a genuinely brutal day, say five back-to-back meetings before noon, this is what it looks like in practice. You list only three tasks, you protect the single open ninety-minute gap for task one, and you let the collaboration window absorb every “quick question” until the afternoon. The list survives the day because it was built to flex, not because the day cooperated.

The version of this that took me longest to get right was working across time zones. For about six months on a team spread from Lisbon to the U.S. west coast, my old habit was to keep a chat tab open all day so I would not miss anything. The cost was that task one never got a clean run, because a reply at 10:15 and another at 10:40 quietly shredded the morning. The fix was a single fixed late-afternoon window, the two hours when both Europe and the early-rising west coast were awake, with one plain rule attached: replies land then, not before. Nobody minded the wait once it was predictable, and the morning block finally held because the messages now had a named time they would be answered.

When the Ivy Lee Method Does Not Fit

No single planning method suits every role, and it is worth knowing the edges before you commit. The Ivy Lee Method struggles in at least three situations. First, genuinely on-call roles, on-call engineering, frontline support, anything where an emergency can erase your planned list at any hour, where the method works best as a secondary anchor for the hours you do control rather than a rigid daily contract. Second, highly creative or research work with unpredictable time demands, where a single task might expand to fill three days or collapse in twenty minutes, which makes a fixed six-item daily plan a poor fit for the actual shape of the work. Third, roles dominated by external blockers, where progress depends so heavily on other people’s responses that any list you write in the evening is invalidated by mid-morning. If your week looks like one of these, treat the method as a lightweight focus aid for your controllable hours, not as your primary operating system.

What Not to Do With Your Ivy Lee List

Don’t write your Ivy Lee list during a video call, since half your attention produces a half-baked plan. Don’t add tasks mid-morning just because a message surfaced something urgent. And don’t substitute checking email for completing task one.

How Does the Ivy Lee Method Compare to Other Systems?

The Ivy Lee Method differs from the 1-3-5 Rule, ABC Method, Eat That Frog, and the MIT Method by enforcing strict sequential focus on six ranked tasks rather than allowing flexible task selection. The table below puts it head to head with its four closest daily-list rivals, and the prose that follows places the Eisenhower Matrix, a triage tool rather than a daily list, alongside it.

Feature	Ivy Lee Method	1-3-5 Rule	ABC Method	Eat That Frog	MIT Method
Daily task count	6 max	9 (1 big, 3 medium, 5 small)	No cap (every task graded)	1 named (the “frog”)	1 to 3 priorities
Sorting method	Ranked by importance	Categorized by size	Graded A, B, C by priority	Hardest, highest-impact first	Single highest-impact task
Sequential order enforced?	Yes, strict	No	Within grades only	First task only	First task only
Planning timing	Evening before	Flexible	Flexible	Flexible	Flexible
Best for *	Focus and overwhelm reduction	Mixed task sizes	Long, mixed-priority lists	Beating procrastination	Protecting one big priority
* Based on conventional positioning in productivity writing; no head-to-head trial data. Full walkthroughs: 1-3-5 Rule, ABC Method, Eat That Frog, MIT Method.

Two of those columns deserve a sentence of interpretation. Eat That Frog fixes only the first task of the day, eating the hardest, highest-impact “frog” first, and leaves the rest of the day unsequenced. The Most Important Task approach, often shortened to the MIT Method, sits closest to Ivy Lee but commits to just one to three priorities rather than a ranked six. Both decide what you start with and stay quiet about the sequence after, which is exactly the gap Ivy Lee fills.

The table above maps Ivy Lee against its four nearest daily-list rivals on the dimensions that matter for daily planning, and the prioritization methods complete guide places all of these methods in one Goals and Progress framework so you can see where each fits before you commit. The “best for” row reflects how each method is conventionally positioned in productivity writing rather than head-to-head trial data. Ivy Lee is built around a single ranked sequence, while the 1-3-5 Rule is explicitly sized for a mix of large and small work. The Eisenhower Matrix sits in a different category again: it sorts tasks into urgency-and-importance quadrants with no fixed daily cap, which makes it a triage tool for deciding what to drop or delegate rather than a daily execution plan. That is why it pairs with Ivy Lee instead of competing with it, a point the next paragraphs return to.

How each combines with the Ivy Lee Method is worth a sentence on its own. The 1-3-5 Rule works better when your day involves a genuine mix of large and small tasks, so you might use it instead of Ivy Lee on varied days rather than alongside it. The urgency-importance sorting of the Eisenhower Matrix pairs cleanly with Ivy Lee: run it during your weekly review to decide what deserves your time at all, then feed the survivors into your nightly list. The frog-first approach popularized by Brian Tracy tells you what to do first but stays quiet about what comes after, so it slots in naturally as the logic for picking your task one. The Ivy Lee Method’s advantage is that it provides a complete daily execution plan, not just a starting point.

If you’re interested in a constraint-based approach centered on your single highest-impact task, see our guide to single-priority task selection, which goes deeper on choosing one task over a ranked list.

What Are the Most Common Ivy Lee Method Mistakes?

Writing vague tasks is the fastest way to sabotage the Ivy Lee Method. “Work on marketing” isn’t a task, it’s a category. Your list should contain specific, completable actions: “Draft the March newsletter intro” or “Create three social media graphics.” Vague tasks invite procrastination because your brain doesn’t know where to start.

Another common trap: listing only easy tasks. It feels great to check off six simple items, but that means you avoided the work that actually moves things forward. In a series of behavioral experiments reported in Judgment and Decision Making, Rusou, Amar, and Ayal observed that people tend to prefer smaller tasks even when larger ones would be more valuable, a measured behavioral pattern rather than a fixed cognitive law [9]. Make sure at least two of your six are substantial.

Planning in the morning instead of the evening is a third mistake. Morning planning eats your best cognitive hours and misses the sleep benefits of evening list-making. You also lose the “pre-decided day” advantage. Instead of starting with task one immediately, you spend twenty minutes deciding what to work on.

And if a task keeps rolling forward for three or more days? That’s a signal. Either it isn’t truly important (cut it), it’s too big (break it down), or you’re avoiding it (make it task one tomorrow). Persistent task rollover on an Ivy Lee list is diagnostic information about task sizing or priority, not a sign of failure.

Ramon’s Take

I’ve tried dozens of productivity systems over the years – GTD, bullet journaling, apps with more features than I can count. The Ivy Lee Method is the one I keep coming back to, and I think the reason is embarrassingly simple: it doesn’t let me hide from what matters. When you’ve only got six slots, you can’t bury the hard task under twelve “quick wins” and pretend you had a productive day. I use a plain index card on my desk. Not Notion, not Todoist, not a Kanban board – a card. The physical artifact matters because I can’t accidentally open Twitter when I check my card. My rule is to write the list within five minutes of closing my laptop each evening, and I pair it with the Eisenhower Matrix during my Friday weekly review to decide which tasks deserve a spot on next week’s lists. It’s not perfect for every situation. On days packed with meetings, I sometimes only list three or four items, and that’s fine. But as a daily operating system for remote work, nothing I’ve found beats the discipline of six ranked tasks and a pen.

Conclusion: Start With Six Tasks Tonight

The Ivy Lee Method for remote work succeeds because it respects a basic truth about productivity: you don’t need more options, more apps, or more time. You need fewer decisions and a clear sequence. For remote workers who lack the structure an office provides, writing six ranked tasks each evening creates an anchor that replaces the morning commute, the boss walking past your desk, and the natural rhythm of an office day. At Goals and Progress, we treat that evening list as the smallest unit of a larger system, the place where long-term goals finally meet what you actually do tomorrow. Evening planning with the Ivy Lee Method turns tomorrow from an open question into a decided sequence.

Built into a daily routine you actually keep, a hundred-year-old technique written on an index card still outperforms the latest productivity app, because decisions, not tools, are the bottleneck. For how this nightly habit fits into a broader workflow, our time management techniques guide covers the wider toolkit.

Next 10 Minutes

• Grab a notecard or open a blank note. Write down the six most important tasks you need to finish tomorrow. Rank them one through six.
• Place the list where you’ll see it the moment you sit down to work, taped to your monitor, on your keyboard, or as your default task app screen.
• Set a recurring daily reminder for your chosen planning time, ideally within 30 minutes of when you normally stop working.

Do that one thing tonight and tomorrow stops being a question you answer all day. It becomes a sequence you already decided.

This Week

• Practice the full five-step evening process each night for five consecutive workdays. Don’t judge the system until you’ve given it a full week.
• Track which tasks you finish and which roll forward. At the end of the week, review the pattern and adjust your task sizing.
• Identify your collaboration window, the one- to two-hour block each day when you’ll batch all reactive, team-facing work.

There Is More to Explore

The Ivy Lee Method is one piece of a larger prioritization toolkit. If you want a similar constraint-based approach with a different task structure, the 1-3-5 Rule offers an interesting variation. For how evening planning fits into a full daily routine, the guide on daily planning methods that work covers the spectrum. And to build the longer focus blocks your ranked list is meant to protect, the deep work strategies complete guide goes further on sustained concentration.
