What one missed day does
In a UCL study of people forming a new daily habit, missing a single day did not materially affect habit formation. It looked at single missed days, not longer breaks.
So a missed day is a moment to use your plan, not a reason to start over. To see where your total days sit on the research ranges, use the habit timeline.
A plan for bad days and missed days
A normal version
What you do on an ordinary day: read for 20 minutes, practise for a quarter of an hour.
A minimum version
The smallest version that still counts: read 1 page, play one scale. On a bad day you do this one, and the day still counts in your tracker.
A plan for a missed day
A 2006 meta-analysis of 94 independent tests found that if-then plans ("If situation Y happens, then I will do X") had a medium-to-large effect on reaching goals (d = .65). The plan maker fills in one for you: “If I miss a day, then I will do the minimum version the next day.” Change it to fit your week.
The same moment each day
Habits form as people repeat the same response in the same context. To link your habit to something you already do, stack it or make it easier to start.
What happens to what you type
Your plan stays in this browser and is never sent anywhere. “Start tracking” saves the habit with your minimum version and your missed-day plan in the habit tracker on this device only. After a missed day, the tracker shows your plan.
