This book completely changed how I approach habit formation. The concept of "1% better every day" is simple yet profound. Clear's explanation of the habit loop (cue, craving, response, reward) provided me with a framework to understand my own behaviors.

What stood out most was the idea of identity-based habits - focusing on who you wish to become rather than what you want to achieve. This subtle shift in perspective has helped me stick to my reading and exercise routines much more consistently.

The writing is clear and practical, with numerous real-world examples that make the concepts easy to grasp and apply. Highly recommended for anyone looking to make lasting changes in their life.
