This book is the worst one I have ever read, I've read every one. What a waste of time, there was some good history in it, but that was about it. My advise don't waste your money get something else more worthy. But if it's free download it and see for yourself..... my opinion you will be glad that at least you've not paid for. So here are the reasons why:1. Author uses too many words only to say he's using them right.2.
Bad review
