Query: Read It Over and Over Again.

A dear friend of mine gave me this book for Christmas last year. I value his opinion, but had told myself just the day before as I looked at my nightstand, "The last thing I need is another self-help book." Well, I was wrong. This is an amazing book. I read it through once. Then I went back and started working the exercises. Then I started reading a chapter each morning to motivate me. I've never read "The Secret," but from my understanding, this is "The Secret" with a business slant. The Success Principles is a compilation of the best parts of self-help, motivational, and good business practices books. I have referred the book to many people and have personally bought six copies to give to friends.
