"Atomic Habits" is a book by James Clear that focuses on the power of small, incremental changes in behavior. Clear argues that tiny habits, when consistently practiced, can lead to significant improvements over time. He emphasizes the importance of understanding the systems behind habits rather than just setting goals, suggesting that small adjustments can create a compounding effect on personal growth. The book outlines a four-step framework for building better habits: cue, craving, response, and reward. Clear provides practical strategies for habit formation, such as the "two-minute rule," which encourages starting with small actions to make habits easier to adopt.
