Query: Worst book you could ever buy

I have never written a review for anything, but this book requires one. Don't get me wrong, I admire this guy. But there is absolutely nothing you can gain from this book other than how to make millions in a book deal, even if the book doesn't deserve it. He has spent more time on his introduction than on his topics. He might not have spent even five minutes on each topic. (You can't believe the number of topics he has covered). Each topic is a one liner like he gives in his Apprentice show. If you buy this book even after reading this review you deserve what you get, just like I did buying the book after reading one of the negative reviews.
