The Power of HabitThe Power of Habit
Duhigg explains the science of how habits work and how they can be changed. At the core is the 'habit loop': a cue triggers a routine that delivers a reward, and over time the brain automates the cycle. By keeping the cue and reward but swapping the routine, habits can be rewired. He also explores keystone habits that ripple into other areas, and how habits shape individuals, organizations, and societies.

The 3 big ideas from The Power of Habit
Every habit is a loop
Habits run on cue, routine, and reward. Recognizing the three parts of the loop is the first step to understanding and changing any habit.
Change the routine, keep cue and reward
You rarely extinguish a habit outright. Duhigg's golden rule is to keep the same cue and reward but insert a new routine in between.
Keystone habits create ripple effects
Some habits, like regular exercise or family dinners, trigger widespread positive change in other areas. Focusing on these high-leverage habits can transform a whole life or organization.

FAQ
What is the habit loop?
Duhigg's model of how habits work: a cue triggers a routine that produces a reward. Repeated, the brain automates the loop — and understanding it lets you redesign the routine.
Is The Power of Habit worth reading?
Yes if you want the science and stories behind why habits form and how they change. It pairs well with Atomic Habits, which is more tactical and how-to focused.
How do you change a habit according to the book?
Identify the cue and the reward driving the habit, then deliberately substitute a new routine that delivers a similar reward. Belief and supportive community help the change stick.
