James Clear

Clear's argument: you don't rise to the level of your goals, you fall to the level of your systems. Small habits compound, the four laws (make it obvious, attractive, easy, satisfying) design behavior, and the deepest change is identity — becoming the kind of person who does the thing.

The Solution section maps his four laws straight onto features: Pulse makes the right move obvious, two-tap follow-through makes it easy, Layers and Rhythm make it attractive, a logged kept-word makes it satisfying. And the whole promise is identity-based — not 'be more productive,' but become, by evidence, the person people can count on.
