Plz do not buy this book. I read CB s book since they are entertaining. But this one is disastrous. I think CB is best when he writes about a simple story in an entertaining and humorous way- ex; 5 point someone and 2 states were really good since both of them were non-serious and did not bring out any social moral issues, politics etc. But whenever CB tries his hand at serious stuff ex- 3 mistakes and revolution 2020, he isnt good at it.
