Atomic Habits
The most popular book on habit-building: how small changes compound into remarkable results, and how bad habits break down.
The atomic idea
Small habits are "atomic" — tiny on their own, yet they build enormous relative improvement when they compound over time. The difference between 1% better and 1% worse each day decides victory or defeat over months.
Identity before goals
Improvement doesn't come from a goal like "I want to lose weight" but from changing your identity: "I am someone who moves daily." A habit reinforces identity, and identity cements the habit.
The four laws
Make it obvious (cue), attractive (craving), easy (response) and satisfying (reward). To break a bad habit, invert each law.
Design the environment
Your environment drives behaviour more than you think. Put the book nearby and reduce access to distractions so the good habit becomes the easy choice.
Systems over goals
Failing to stick with something is usually a system problem, not a willpower problem. Build the system and the system produces the result.
