I started this book back in 2015 but I got distracted and set it aside. I was happy to pick it up again and I found myself trying to remember what pulled me away. This book is fantastic. It's an easy read with many entertaining stories and anecdotes. Duhigg takes us through the science, psychology, and even the "spirituality" of habits. Throughout we see the Habit Loop. Every habit contains these three elements: a cue, a routine, and a reward. The cue—the thing that triggers or sparks the habit—can be just about anything but can be categorized into five different sorts of cues: location, time, emotional state, other people, and/or an immediately proceeding action. The routine is the habit itself, like drinking a cup of coffee, driving to work, gambling, viewing pornography, yelling at your spouse, or forgiving and turning the other cheek. The reward is just what it sounds like. It's the good thing at the end of the habit loop. It's a burst of energy, it's excitement, it's a feeling of peace or control, a sense of self-worth, etc. Whatever it is, you want more of it. So the next time you're triggered, the next time the cue arises, you remember the actions that gave you the reward. You keeping doing them over and over until they become routine, until they become habits, until you don't even have to think about them any more. In order to change a bad habit you hijack the loop. You keep the cue and reward but you change the routine. This, however, isn't enough. You also need something we can call "faith." It's the belief that change is possible. And this faith is fostered in community. We are more likely to change our habits if we make the efforts with others. They help us to believe that change is possible. Duhigg is a masterful storyteller. He takes us from NFL games to aluminum factories, from Olympic races to night terror murders. Strange stories all built on stranger things: Habits. I recommend this book to anyone looking to make a change.
