The Power of Habit

Charles Duhigg

An exploration of the science behind why habits exist and how they can be changed. Duhigg reveals the habit loop and how it operates in individuals, organizations, and societies.

The "cue → routine → reward" loop is deceptively simple but once you see it, you notice it everywhere in your life.

The stories are what make this book work — from Alcoa's safety transformation to how Target predicts pregnancy, every example illuminates the theory.

The keystone habits concept was the most actionable insight: change one core habit and it cascades into transforming many others.

• Habits are not destiny — they can be changed once you understand the loop.
• Keystone habits create chain reactions that transform everything.
• Willpower is a muscle — it gets tired but can be strengthened.
• Small wins create momentum for larger transformations.
