Bests & Worsts Reviews from Amazon

I feel like I have been taking in by a scam. This extremely light book basically lists 4 main principles including: sleep, nutrition, exercise, meditate - and lists a bunch of tips and scientific "did you knows" about each topic. That is it! There is nothing more. This book feels like some kind of Ryan Holliday style attempt to hack amazons algorithms. Although... while Ryan's books are decent... this is a sham. I literally isn't what it says on the tin. You just read a bunch of stuff you know... and a few things you didn't... about sleep, nutrition, exercise and meditation. The power of habit - this ain't.
