Atomic Habits

Atomic Habits: Tiny Changes, Remarkable Results translates academic research on habit formation into a practical, mass-market system. Its central image is the "1 percent better" principle, that marginal improvements, compounded over time, produce results far out of proportion to any single effort.

The book's intellectual core is identity-based habits. Rather than starting from outcomes or processes alone, Clear argues that lasting change works from the inside out, by asking what a certain kind of person would do and letting each repeated action cast a vote for that identity. His Four Laws of Behavior Change, to make a habit obvious, attractive, easy, and satisfying, operationalise this into a teachable framework for building good habits and breaking bad ones.

Writing as a synthesiser of behavioral science rather than an original researcher, Clear gives the mind-power lineage one of its cleanest secular statements that who a person believes themselves to be precedes and shapes what they do.
