Atomic Habits: (H) An Easy & Proven Way to Build Good Habits & Break Bad Ones by James Clear

Atomic Habits is James Clear’s practical guide to making small behavioral changes and building systems that support them. It shifts attention from ambitious goals alone to the routines and environments that shape everyday actions.

Clear draws on ideas from psychology, biology and neuroscience, alongside examples from a range of people and professions. Topics include making time for habits, working with motivation, changing the environment and returning to a routine after a setback. It is a general personal-development book, not a medical treatment program.
