The No Zero Days Technique: The Reddit Comment That Launched a 100,000-Person Movement
In 2013, a struggling college student posted on Reddit asking for help. He’d moved away from home hoping a change of scenery would fix his apathy, and it hadn’t. A user named /u/ryans01 replied with a comment that would go on to be saved, shared, and screenshotted hundreds of thousands of times. The core idea: stop having zero days. A zero day is any day you do absolutely nothing toward your goal. The no zero days technique asks you to do at least one small thing, every single day, no matter how tiny. Research from Phillippa Lally’s team at University College London found that consistent daily repetition is the single strongest predictor of whether a behavior becomes automatic [1]. So what happens when you commit to never scoring a zero again?
No Zero Days Technique is a consistency-building method where a person commits to performing at least one small action toward a goal every day, so that no day passes with zero progress. The bar is set intentionally low – a single pushup, one sentence of writing, five minutes of study – to remove the friction that stops people from starting.
Who this is for: People who keep restarting the same goal from zero, who break streaks and give up entirely, or who want a consistency system that survives bad weeks. It is not the right approach when the problem is output quality rather than showing up – if you already write daily but the writing is weak, a daily minimum habit won’t fix that. It is also not ideal for people who find daily commitments anxiety-inducing rather than motivating; in that case, a weekly goal with flexible scheduling tends to produce better results. And it works poorly for goals that require long uninterrupted sessions to produce anything useful, where a two-minute daily minimum cannot create meaningful forward motion.

Key Takeaways
- A zero day is any day with no progress toward a goal – the no zero days technique eliminates those days.
- Habits take a median of 66 days to become automatic, with a range of 18 to 254 days [1].
- Missing one day doesn’t materially disrupt the habit formation process, according to UCL research [1].
- Broken streaks reduce subsequent engagement – the streak itself becomes the goal [4].
- Small wins are the single strongest driver of positive inner work life, per Harvard research [3].
- A daily minimum should take under two minutes – low enough to complete on the worst possible day.
- Simple binary tracking (did it/didn’t) outperforms detailed metrics during the early weeks of habit formation [5].
- The Momentum Ratchet framework raises the daily floor by one small notch every two weeks.
- Shrinking a behavior to its smallest version increases the likelihood of consistent follow-through [2].
Why Does Minimum Viable Effort Beat Ambitious Daily Targets?
The no zero days technique works not in spite of its low bar, but precisely from that low bar. Stanford behavior scientist BJ Fogg spent over 20 years studying why people fail at habit change and arrived at a clear conclusion: most people aim too high when trying to form a new habit, which leads them to quit [2]. His Behavior Model (B = MAP) shows that any behavior happens when motivation (M), ability (A), and a prompt (P) line up at the same moment. By shrinking the behavior down to something tiny – one pushup, one paragraph, one minute of meditation – you dramatically increase ability and reduce the motivation required to act.
The no zero days technique succeeds by lowering the activation threshold for daily action below the point where resistance kicks in. That’s the mechanism. And it’s backed by decades of behavioral research.
Phillippa Lally and her team at University College London tested this in a 2010 study published in the European Journal of Social Psychology. They tracked 96 participants who each chose a new daily behavior and measured how long it took for that behavior to feel automatic. The median was 66 days, but the range stretched from 18 to 254 days depending on the person and the complexity of the behavior [1]. The most relevant finding for no zero days practitioners: missing a single day did not materially affect the path toward automaticity. One missed day didn’t reset the clock.
This aligns with what Teresa Amabile and Steven Kramer discovered through their analysis of nearly 12,000 daily diary entries from 238 professionals across seven companies. Their research found that making progress – even small progress – was the single most powerful event driving positive inner work life [3]. Small wins and major breakthroughs produced nearly identical boosts to motivation and engagement in Amabile and Kramer’s analysis of 12,000 diary entries. The size of the action mattered far less than the fact that forward movement happened at all.
Gardner, Lally, and Wardle reinforced this in their 2012 review of habit-formation psychology in the British Journal of General Practice, concluding that repetition in a consistent context is what drives automaticity – not the intensity of each repetition [5]. A single pushup performed every evening after brushing teeth builds the habit pathway just as effectively as a full workout, at least during the formation phase.
How to Set Up a No Zero Days System
Setting up a no zero days system requires three decisions: what you’re tracking, what counts as a daily minimum, and how you’ll record it. Here’s a step-by-step process to get started.
Step 1: Pick one to three goals. Don’t try to run a no zero days system across every area of life at once. Start with one goal. If you’ve already explored habit-based goals versus achievement-based goals, you know the difference between “run every day” and “run a marathon.” No zero days works best with habit goals – the ones where showing up daily is the point.
Step 2: Define a daily minimum. This is the smallest possible action that still counts as progress. It should take under two minutes and require almost no willpower. If the goal is writing a book, the daily minimum might be one sentence. If the goal is getting fit, it might be one pushup. A no zero days daily minimum must be small enough to complete when sick, traveling, exhausted, and having the worst day of the year.
Step 3: Choose a binary tracking method. Research on habit formation suggests that simple binary tracking – did you do it or didn’t you – tends to support longer adherence than detailed metrics during the early weeks of a new behavior [5]. A wall calendar with Xs, a simple checklist app, or a spreadsheet with 1s and 0s all work. The format matters less than the consistency of recording. You need a system that lets you see the streak at a glance. For a deeper look at tracking systems, see our complete guide to goal tracking systems.
Step 4: Anchor it to an existing routine. Fogg’s research demonstrates that habits stick best when they’re tied to an existing behavior [2]. “After I pour my morning coffee, I’ll write one sentence.” “After I brush my teeth at night, I’ll do one pushup.” This anchoring removes the need to remember or decide when to act.
| Goal | Daily Minimum (Under 2 Min) | Anchor Behavior |
|---|---|---|
| Write a novel | Write one sentence | After morning coffee |
| Get stronger | Do one pushup | After brushing teeth |
| Learn Spanish | Review one flashcard | After lunch |
| Build a side business | Send one email or write one note | After arriving at desk |
| Read more | Read one page | Before bed |
How to Define the Right Daily Minimum Threshold for Your Zero Day Rule
The daily minimum is where most people get the no zero days technique wrong. They set the bar at “30 minutes of focused work” or “a full workout” and then wonder why they start accumulating zero days within two weeks. The threshold needs to feel almost embarrassingly easy.
BJ Fogg calls this a “Starter Step” – the first two seconds of the behavior you want to build [2]. The logic is counterintuitive: if you want to run every day, the daily minimum is putting on running shoes. Not running a mile. Not even walking to the end of the driveway. Just shoes on feet. Once the shoes are on, behavioral momentum takes over and you’ll usually do more. But the commitment is only to the shoes.
Starter Step is BJ Fogg’s term for the first two seconds of a target behavior – the smallest possible unit of action that initiates the habit. A Starter Step is not the full behavior; it is the trigger-action that makes the full behavior more likely to follow.
Behavioral momentum is the psychological effect by which completing a small initial action lowers the friction required to continue. The first action reduces perceived effort for subsequent actions within the same session, making it more likely a person will do more than the minimum once they start.
This works through a psychological principle called behavioral momentum. Once you take the first small action, the friction to continue drops dramatically. Gardner, Lally, and Wardle’s review of habit-formation research found that the act of initiating a behavior in a consistent context matters more for habit development than the duration or intensity of the behavior itself [5]. Behavioral momentum means the hardest part of any daily habit is the first five seconds – not the last five minutes. You’re not tricking yourself. You’re engineering the conditions for action by removing every possible barrier.
Test a daily minimum with this question: “Could I do this if I were sick, traveling, exhausted, and having the worst day of the year?” If the answer is no, shrink it further. The daily minimum is a floor, not a ceiling. On good days, you’ll blow past it. On terrible days, you’ll just barely clear it. Both count equally. Both keep the streak alive. Both register as non-zero. And that’s the entire point – you’re building the identity of someone who shows up every single day, which connects directly to the follow-through framework we cover in detail elsewhere.
What Should You Do When You Break a Streak?
You’ll break a streak. That’s not pessimism – it’s probability. The question isn’t whether it happens, but how you respond. And the research here is clear: the response matters more than the break itself.
Jackie Silverman at the University of Delaware and Alixandra Barasch at the University of Colorado Boulder published a study in the Journal of Consumer Research showing that broken streaks significantly reduce subsequent engagement with a behavior [4]. When people see a broken streak in their log, they disengage – not from the behavior getting harder, but from the streak itself having become a goal. Losing it triggers what psychologists call the “what-the-hell effect”: the rationalization that since the streak is already broken, there’s no point in continuing today [6].
The what-the-hell effect is a psychological response to a perceived failure where a person abandons a behavioral goal entirely after one violation, reasoning that the damage is already done. Cochran and Tesser (1996) documented this pattern in goal-regulation research: missing once increases the probability of missing again because the person reframes the goal as already lost [6].
That’s the trap. The antidote is a concept called the “Never Two” rule: you can miss one day, but you never miss two in a row. Lally’s UCL study found that one missed day did not disrupt the path to automaticity [1]. The streak is a tool, not the goal. If you break it, the only thing that matters is whether you show up tomorrow.
Silverman and Barasch found a second key result: that the negative effect of a broken streak was reduced when people could “repair” it – for example, by allowing a makeup day or reframing the break as a pause rather than a failure [4]. Build this into a no zero days system. If you miss a day, do a double minimum the next day. Not as punishment, but as a signal to the brain that the pattern is still intact. This kind of psychological recovery connects to the broader science behind accountability and motivation.
If streaks break repeatedly rather than occasionally, that is a different problem than a single missed day. Repeated breaks usually mean the daily minimum is set too high – not a motivation failure. When the same day of the week keeps becoming a zero day (a busy Tuesday, a weekend where the anchor routine disappears), the minimum needs to shrink further, or the anchor behavior needs to change. Treat repeated breaks as diagnostic data: the system is telling you the floor is in the wrong place. Lower it until the streaks hold, then ratchet it back up slowly.
No Zero Days Streak Recovery Checklist
Daily Progress Tracking Without Obsessing Over the Number
Streak tracking is a double-edged tool. It motivates action, but it can create anxiety. When a 47-day streak becomes more important than the underlying habit, the purpose has been inverted. The streak is supposed to serve the goal, not replace it.
Research supports using simple binary tracking during the formation phase. Gardner, Lally, and Wardle’s review of habit-formation psychology notes that the key driver of automaticity is the repetition of a behavior in a stable context, not the measurement of its intensity or duration [5]. Counting reps, minutes, or calories introduces judgment. Binary tracking removes it. You either did something or you didn’t. There’s no room for “not enough.”
Here are practical tracking approaches ranked by simplicity:
| Method | Best For | Risk Level for Obsession |
|---|---|---|
| Paper calendar with X marks | Single habits, visual learners | Low |
| Simple checklist app | Multiple habits, phone users | Medium |
| Spreadsheet with 1/0 values | Data-oriented people | Medium |
| Dedicated streak app with notifications | People who need external prompts | High |
| Detailed metrics dashboard | Advanced users past formation phase | High |
The comedian Jerry Seinfeld popularized a version of this approach, known as “Don’t Break the Chain,” where he placed a large wall calendar in a visible spot and marked every day he wrote jokes with a big red X. The visual chain of Xs became its own motivation. But note that Seinfeld was tracking a binary – did he write, yes or no – not how many jokes he produced. Jerry Seinfeld’s “Don’t Break the Chain” method tracks a binary (wrote/didn’t write), not output volume – the consistency drives the quantity over time.
| Method | Core Idea | Key Difference from No Zero Days |
|---|---|---|
| No Zero Days Technique | Never let a day pass with zero progress; set an intentionally low daily minimum | Explicit minimum floor plus a structured ratchet for raising it over time |
| Don’t Break the Chain (Seinfeld) | Mark every day you complete the task; protect the visual chain | No defined minimum – any effort counts, but the chain becomes the goal without a recovery protocol for breaks |
| Atomic Habits Two-Minute Rule (Clear) | Shrink every new habit to under two minutes to make starting easy | Focused on starting the behavior, not on the chain of days; no progressive floor-raising framework |
If you notice anxiety creeping in around the streak number, shift to weekly reviews instead of daily checks. Lally’s research showed that missing an occasional day didn’t derail long-term habit formation [1]. Missing one day out of seven is still a strong week. So focus on the week-level pattern rather than the day-level number. For a system that helps you create effective commitment structures around tracking, read about commitment devices that help you stick to goals.
Once your tracking log shows 14 consecutive non-zero days, that is the signal to move to the next phase. That is exactly when the Momentum Ratchet applies: the behavior is stable enough to raise the floor without triggering resistance.
The Momentum Ratchet: How to Raise the Daily Floor Over Time
The no zero days technique gets you started. But staying at “one pushup per day” forever won’t get you strong. You need a structured way to gradually increase the daily minimum without triggering the resistance that killed previous attempts. At goalsandprogress.com, we call this framework The Momentum Ratchet.
A ratchet is a mechanical device that allows movement in only one direction. The Momentum Ratchet works the same way for a daily floor: it can go up, but it never goes back down to where it started. Here’s how it works:
- Start with a Starter Minimum. This is the embarrassingly easy daily action from step two above. Commit to this for 14 consecutive days.
- After 14 days, ratchet up by one notch. One pushup becomes five. One sentence becomes one paragraph. One flashcard becomes three. The increase should feel only slightly harder than what you were doing.
- Hold the new level for 14 more days. This gives the new minimum time to settle into the routine before another increase.
- Repeat the ratchet. Every two weeks, nudge the floor up by one small increment. Five pushups become ten. One paragraph becomes two.
- Cap the daily minimum at 50% of an ideal session. If an ideal workout is 30 minutes, the daily minimum should never exceed 15 minutes. The minimum exists to keep the streak alive on hard days. If it’s set too high, zero days start piling up again.
| Week | Writing Goal Example | Fitness Goal Example |
|---|---|---|
| Weeks 1-2 | 1 sentence | 1 pushup |
| Weeks 3-4 | 1 paragraph | 5 pushups |
| Weeks 5-6 | 2 paragraphs | 10 pushups |
| Weeks 7-8 | Half a page | 15 minutes of exercise |
| Weeks 9-10 | One full page (cap) | 20 minutes of exercise (cap) |
The Momentum Ratchet raises a daily minimum by one small notch every 14 days, capping at 50% of an ideal session to prevent the floor from becoming a barrier. Each increase is small enough that the brain doesn’t register it as a new, threatening demand. You’re not starting a new habit – you’re slightly adjusting an existing one. And since Lally’s research shows the automaticity curve is asymptotic rather than linear [1], each additional day of practice makes the next day a little easier. The ratchet rides this curve upward.
Practitioner evidence supports the gradual-floor approach. James Clear, who tracked his own writing and fitness habits across several years while building an audience of millions, reports that the habits that persisted longest were those held at a minimum low enough to survive travel weeks and sick days – only raised once the lower level felt automatic. This aligns with what the academic research predicts: keep the floor survivable, raise it only after the behavior has stabilized.
This connects naturally to the broader goal-setting process. If you’re building a system of habit formation, the Momentum Ratchet gives you a clear rule for when and how to increase intensity without relying on motivation or willpower.
Ramon’s Take
I think the no zero days concept is the single most underrated productivity idea on the internet, and it came from a Reddit comment, not a bestselling book. My personal stance: the daily minimum should feel so small that it’s almost insulting. If you feel proud of your minimum before you’ve even started, it’s too high. I set my writing minimum at one sentence per day for six months before I raised it, and that single decision produced more finished work than any ambitious schedule I’d ever attempted. The technique isn’t about the minimum – it’s about the unbroken chain of identity that forms when you never let a day pass empty. What surprised me most was how often the “just one sentence” turned into 500 words. Something about removing the pressure to perform well freed up the ability to perform at all. I’ve watched people try to start with 30-minute daily commitments and flame out inside of two weeks, and I’ve watched people start with one pushup and still be going eight months later. The pattern is always the same. The people who survive the first 90 days are the ones who picked a minimum so low that their friends laughed at it. That’s how you know you got it right.
No Zero Days Technique Conclusion: Start Today, Stay Tomorrow
The no zero days technique is not a productivity system. It’s an identity system. Every non-zero day is a vote for the kind of person you’re becoming – someone who shows up, no matter how small the action. The research from Lally, Fogg, Amabile, and Silverman all points to the same conclusion: consistency beats intensity, and the threshold for meaningful daily progress is far lower than most people assume. The no zero days technique works through consistency of action rather than intensity of effort for long-term habit formation and goal progress.
You don’t rise to the level of your goals. You fall to the level of your daily floor. Set it low enough to never miss, and then ratchet it up over time.
Next 10 Minutes
- Pick one goal you’ve been struggling with and write down a daily minimum that takes under two minutes.
- Do that daily minimum right now, before closing this page.
- Mark today as day one on a calendar, notebook, or phone.
This Week
- Set up a binary tracking system – a wall calendar, a simple app, or a spreadsheet with 1/0 values.
- Anchor the daily minimum to an existing routine (after coffee, after brushing teeth, after lunch).
- Commit to seven consecutive non-zero days. At the end of the week, review: did you hit seven out of seven? If not, was the minimum too high? Adjust and start week two.

Frequently Asked Questions
What is the no zero days technique and where did it originate?
The no zero days technique is a consistency method where a person commits to doing at least one small action toward a goal every single day, so that no day passes with zero progress. It originated from a 2013 Reddit comment by user /u/ryans01 and was later reinforced by behavioral research from BJ Fogg and Phillippa Lally showing that daily repetition in a stable context is the primary driver of habit formation [1][2].
How small should a daily minimum action be for no zero days?
A daily minimum should take under two minutes and require almost no willpower. BJ Fogg calls this the Starter Step – the first two seconds of the desired behavior [2]. The test is whether the action could be completed when sick, traveling, exhausted, and having the worst day of the year. If not, it needs to be smaller.
Does doing the bare minimum every day actually lead to real progress toward goals?
Yes. Amabile and Kramer’s analysis of nearly 12,000 daily diary entries at Harvard found that small progress events were the strongest driver of positive inner work life – nearly as powerful as major breakthroughs [3]. On most days, people exceed the minimum once they start – behavioral momentum lowers the friction to continue after the initial action.
What is the best way to recover after breaking a no zero days streak?
Apply the Never Two rule: miss one day but never two in a row. Lally’s UCL research found that a single missed day does not materially affect the habit formation process [1]. Consider doing a double minimum the following day to signal the pattern is still active. Silverman and Barasch found that streak repair mechanisms reduce the motivational damage of a broken streak [4].
How long does the no zero days approach take to become automatic?
The timeline depends heavily on the complexity of the target behavior. Lally et al. (2010) found that simpler behaviors – like drinking a glass of water with breakfast – reached automaticity near the low end of the 18-to-254-day range, while exercise-based habits clustered toward the higher end [1]. This is why the no zero days technique keeps the daily minimum so small during the formation window: a one-pushup minimum is more like a “drink water” habit than a “go to the gym” habit in terms of complexity, and therefore builds automaticity faster. The Momentum Ratchet then raises the floor gradually once the lower behavior has already become automatic.
What should you do when your no zero days tracking method stops working?
If a tracking method stops motivating action – or starts creating anxiety instead – switch formats rather than abandoning the system. The most common sign is that checking the streak number feels stressful rather than satisfying. When that happens, move from daily tracking to weekly reviews: count how many days out of seven you showed up, rather than watching the streak accumulate. This removes the all-or-nothing pressure of the streak while keeping the consistency data visible. A second warning sign is when hitting the minimum feels like a chore rather than a floor. That usually means the minimum has crept too high and needs to be reset lower, not that the entire system has failed.
When should the daily minimum be increased using the Momentum Ratchet?
Hold the current daily minimum for 14 consecutive days, then increase it by one small notch – the increase should feel only slightly harder than what was already happening. Cap the daily minimum at 50% of an ideal session so it remains achievable on the worst days. The 14-day cycle allows each new level to stabilize before the next increase.
Can the no zero days technique be applied to multiple goals at once?
Start with one goal and build consistency before adding others. Once the first habit feels automatic – typically after 8 to 10 weeks of consistent practice – add a second. Running a no zero days system across more than three goals simultaneously tends to dilute focus and increase zero days across all of them, since each additional commitment competes for the same limited daily willpower.
