This book is great in that it finally déculpabilisée me! He explains why it is impossible to completely control our thoughts and shows the excesses of "ready-made" proposed by other books. So it seems more within reach to change things in our lives, more simply, less formatted ... The writing is very fluid, easy to understand, everyone. In fact, what he says sounds almost too simple, it is only because we have forgotten a lot of obvious things and that we let too often guided by automation that ultimately we are harmful. I highly recommend, a nice gift for the New Year celebrations.
