The problem with a streak
A streak turns not failing into the goal. While it lasts, it pushes you. The day it breaks, it takes your motivation with it.
A series of seven studies published in 2023 measured it: after a broken streak, people were less likely to continue, even when it broke for something outside their control. The effect softened when there was a way to repair the streak.
What matters is not failing twice
In an experiment with more than 60,000 members of a gym chain, dozens of programmes were tested to increase attendance. The one that worked best was the simplest: encouraging people to come back right after missing a day.
Missing once barely counts. The damage comes when one miss becomes two, and two become a month.
The alternative: weeks
A weekly goal has slack. If you aim for three days and Tuesday falls through, you still have four days to get there. There is nothing to break.
In Welfitlab, days of illness, injury or travel are also marked as a break, and that week's goal adjusts to the days you actually had.
