An incredibly thin book with little useful or applicable advice or ideas. If you’ve read any pop-psych or self-improvement type books you’ve come across 90% of this book before. It’s the same tired mix of personal anecdotes, the same handful of studies (the marshmallow test! skinner box! etc) and the same attempt to stretch out quite a thin premise over a few hundred pages. A real shame that it comes across as vacuous as a ted talk.
