This book is different than the generic self help books that we have all read. David didn't just regurgitate what everyone else said about self improvement. He invented his own methods through trial and error. He is also not afraid to tap into something that our society has just about eliminated, negative reinforcement. My self-improvement journey was always hindered by too much positive reinforcement throughout my life. There is a place for this, but sometimes you just have to look in the mirror and call yourself out with brutal honesty, David literally does this daily.
