Hi,
Yes i have read it. I have mixed feelings about it. One the one hand if it can get people to think positively then fine, nothing bad can come of that. But i think there is a "dangerous" element to the book which imply that you just have to think and believe about things for them to magically materialize. Well, let's face it that just won't happen.
A positive outlook, faith in the desired outcome are essential for success, no doubts about that. But that's only one part. If you don't act, take concrete steps towards your goal, then you won't succeed. The book is misleading in that sense. A lot of people want an easy fix and don't want to put the efforts it takes to succeed, the book knows that and plays on it.
Also, a lot of the ideas in that book are nothing new at all and directly taken from classics like Think And Grow Rich by Napoleon Hill. It all has been said before.
I would say read it, but don't think for one moment that checks will magically pop in the mail like the book says...the only thing things that'll pop will be bills!
