How to Build Habits That Stick

Most habit advice is folklore — "21 days," "just be disciplined." This guide is the opposite: the actual behavioral science of how habits form, and the practical methods that follow from it. Everything ties back to named research (Lally's 66-day median, Wendy Wood on context, Clear's habit stacking, Duhigg's loop). Read it as a path, or jump to whatever you're stuck on.

The core idea: a habit is a cue → routine → reward loop that runs with little conscious effort once it's wired in. You build one not by trying harder but by making the cue obvious, the routine small, and the streak visible. The science section explains the mechanism; the practice section turns it into something you can start tomorrow.
