In Atomic Habits, author James Clear references other books I too was influenced by such as Blink by Malcolm Gladwell, How to Fail at Almost Everything and Still Win Big by Scott Adams and The Power of Habits by Charles Duhigg. You know you're in for something special when a book cites multiple other books you already love.

First of all, I love the author's non-biased definition of habits. They are "automatic solutions to reoccurring problems." But whether these habits are good or bad, or beneficial or not, is up to us. We're then introduced to the four laws of building good habits. 1.) Make it Obvious, 2.) Make it Attractive, 3.) Make it Easy, and 4.) Make it Satisfying. The inverse is also true for getting rid of bad habits—make it obscure, make it unappealing, make it hard, and make it unsatisfying. Apply these rules and rinse and repeat for however long it takes to change the habit.

It's that simple. But as we all know, changing habits is anything but simple. Atomic Habits is an exploration of personal system hacks for making the changes as simple as possible. The whole effort still requires putting in the work, but for me there's a comfort in knowing that the seemingly impossible is very much possible if given effort and attention.

The most effective way to change your habits is to focus not on what you want to achieve, but on who you wish to become.
The Four Laws of Behavior Change are a simple set of rules we can use to build better habits. They are (1) make it obvious, (2) make it attractive, (3) make it easy, and (4) make it satisfying.
