How change actually happens

People imagine behaviour change as a line going up. It isn't. It's a scatter plot with a trend.

The relapse-prevention model that underpins most modern addiction treatment makes a distinction worth internalising now, before you need it: a lapse is a single instance. A relapse is a return to the old pattern. The thing that turns one into the other isn't the lapse. It's what you conclude about yourself afterwards.

Marlatt called this the Abstinence Violation Effect. If, after a slip, you conclude I'm the kind of person who can't do this, you've just made the next slip more likely — because now there's nothing left to protect. If you conclude that was a specific situation and I can see what led to it, the streak is broken but the project isn't.

This is why this app doesn't do dramatic streak-reset animations, and why we'll ask you to write down what happened rather than how bad you feel about it. Not because your feelings don't matter — because the information is more useful than the verdict.

Expect this to be non-linear. Plan for it. Most people who get where they're going do so on the third or fourth attempt, not the first.

Takeaways

• A lapse is one instance. A relapse is a return to the pattern. What you conclude in between is the hinge.
• "I'm the kind of person who can't do this" is the sentence that does the damage.
• Non-linear is the normal shape. Plan for it rather than being surprised by it.
