Query: DON'T WASTE YOUR MONEY ON THIS BOOK!

Straight and to the point: This book does not reveal anything like the cover specifies, it is a 2 cent piece of crap--just a lot of ideas and nothing that would indicated what the cover specifies, you can get everything in this book from the internet for free; if you want to throw your money down the drain for nothing then buy this book!
