Here's how traditional self-development works in a nutshell:1. The person or a third-party identify a weak area or something "bad" that needs to be immediately fixed.2. The person with the problem comes into contact with the knowledge that can help, motivation ensues.3. The person tries to strong-arm their way through the problem to reach some nebulous end-state.4. The person achieves temporary enlightenment as their goals are achieved or are in the process of being achieved.5. The person loses motivation after a period of time, they start to slip, they end up backsliding into their old ways.6. The person becomes upset with self, wondering why they can't do what they want to do.7. The person starts again, this time with a new method.That cycle of madness ends with this book. Atomic Habits is the key to following through with the methods in all of those other books and programs.The Power of Habit was the cultural awakening. This is the deepening of those lessons in that book.It is by far the best framework that I've seen giving you a way to build great habits. This book is actionable, it's insightful, and it offers ways around your rationalizations so that your habit will begin to lock in and be easier and easier to perform.The best parts of this book:- Why habits and identity are a chicken-and-egg feedback loop with no beginning or end- Why goals are a terrible metric and target for success- Why certain habits are reinforced while others are downplayed- The inevitability of friction in daily life and how to minimize or reduce that friction- How to keep awareness as you begin to integrate a habit and use it as a jumping off point for mastery- The little lessons at the end of the book (the most pragmatic part, little nuggets that can be put into play immediately)If you study this book and implement it, your life will change bit by bit until you're a new person doing new things in a new environment.That sounds worth the price of admission to me. Pick it up, you won't regret it.
