The core idea: a habit is a cue → routine → reward loop that runs with little conscious effort once it's wired in.

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.
