Superhuman by Habbit

The strength of this book is in its practicality. It's not vague on the details. It's specific in its recommendations and tells you how to do each one as well as what to expect, and when to expect it. Which means I can actually implement this stuff. For example, he talks about building a habit of daily meditation. He gives specifics about how to do this. He tells you why you would want to do this from a practical non-"woo woo" perspective. Then he tells you how long you should follow this practice to start to see results.
