It's a strange review to have to write because I read the book as a result of attending a four week course in SUMO with my granddaughter at her Grammar School. I enrolled for the course, Stop, Understand, and Move On and was curious why there'd been a re-think (?) about the change in title. Presumably it was because Stop, Understand & Move On is more child/school friendly.
So, the the book. There's very little scientific research and use of academic thought in this book. We have to accept that it's the thoughts and observations of one man. Which is fine, but it's not comparable to say, The Chimp Paradox in any way. The main messages are similar though - are control of your life, don't wallow (too long) in your own self-pity, stop having an attitude of being a victim of life/fate/other people, seize opportunity and so on. If there's a weakness, it's that the 'how' to do these things is not well explained. If there's a strength, it's the direct, uncompromising nature of the key messages, which I like. For example, when you've finished this book, you might procrastinate, you might do nothing, if you do, don't blame the book, instead, look in the mirror. My final criticism is that the author uses too many examples from his own life and his own experience, which gives a bit of a 'be like me and you'll be fine' feeling.
