Four Laws of Change

James Clear turned decades of behavioral science into four simple levers. Each one targets a different stage of the habit loop, and missing any one can make the habit fall apart:

• Make it obvious — design your space so the cue is hard to miss
• Make it attractive — pair the new habit with something you enjoy
• Make it easy — shrink the action until it is hard to refuse
• Make it satisfying — reward yourself right away so the brain wants a repeat

To break a bad habit, flip each law: make it invisible, unattractive, difficult, and unsatisfying.
