The Power of Habit
Charles Duhigg · 2012
"Habits run on a neurological loop of cue, routine, and reward, and the reliable way to change an existing habit is to keep the same cue and reward while deliberately swapping out the routine in between — not to rely on willpower alone."
Duhigg's core claim is that habits aren't decisions you keep re-making — they're a loop your brain runs on autopilot to save effort: a cue triggers a routine, the routine delivers a reward, and repetition wires the loop so tightly that eventually the cue alone triggers a craving for the reward before the routine even starts.
This is why willpower-only habit change fails so often: it tries to delete the routine but leaves the cue and the craving for the reward fully intact, so the old routine keeps getting pulled back in under stress. Duhigg's 'Golden Rule of Habit Change' instead keeps the cue and the reward exactly the same and only swaps the routine in the middle — which is why, for instance, replacing a stress-triggered snack habit works best when the replacement still delivers a comparable reward (a walk, a call to a friend) rather than just removing the snack and leaving the craving unanswered.
According to Duhigg's 'Golden Rule of Habit Change,' what is the most reliable way to change an existing habit?

Identity-Based Habits
"True behavior change is identity change. If you don't shift how you view yourself, you will eventually sabotage your new habits to align with your old identity."
