I don't leave many reviews but I had to for this book since I felt that I got so much out of it, I might as well tell other people about it. In short, it's a stellar and dense read about what motivates people and our brains, and how we can short circuit that and take advantage of it to our self-discipline. It's important to understand what you are battling in procrastination, perfectionism, distractions, and lack of motivation, and that's all addressed here. Honorable mention on the characterization of motivation as a temporary state of mind, where discipline is more automatic. Then more about habit formation and longer lasting behavior modification. Fascinating section on dopamine control, as well as application of the 40% rule that the military has become famous for.
Far more than you'd expect but still very accessible and applicable. Overall, just fantastic.
