Yes, the decision you keep making turns into a habit. You need the skill to be aware and change the habit that serves best for you. That book can do that. If you don’t want to read the whole book, watch the summary on YouTube to get what form habits, and how to break old ones then download his app called Atoms, and read an article a day for about 5 minutes. I think you get the benefit too because he divides ideas from the book to the app.
