Jerry Seinfeld's "don't break the chain" method became famous for a reason: it works. The power isn't the streak itself — it's the identity that forms around it.
When you complete tasks every day for 10 days, you stop thinking "I need to do this" and start thinking "I'm the kind of person who gets things done." That shift is massive.
Neuroscientists call this habit stacking with identity reinforcement. The streak becomes a symbol of who you are, not just what you do.
In Doneflow, your streak counter is always visible. It's not gamification for its own sake — it's a daily reminder of the identity you're building.
When you break your streak (and you will, everyone does), the key is to restart immediately. Research shows that "missing once" has almost no effect on long-term habit formation. "Missing twice" is where habits begin to deteriorate.
One zero day is a blip. Two is a pattern. Keep the gap to one.
