The secret is an introduction to the law of attraction and it really just teaches you the basics of how thinking positive can help you have the things you desire. I read this book about 4 years ago and it was the start of me and my life changing for the better.
I got it out the library last year. Don't hold your breath. There is no secret. It's one of those you can become a millionaire, a sportstar popstar overnight if you only decide that's what you want and work towards it. So it's just a lot waffle designed to make the author rich. Which presumably it has. I thought it contained some sort of revelation as to how the universe worked. It didn't.
