This book is in the same category as the new book, "The Secret", which seems to be gaining popularity, and is a book you may have heard of. I have read this book as well, and I prefer Bob Proctor's book, personally.
The basic premise behind this book is that thoughts affect things. In other words, what you think of in your mind has a physical effect on the outside world. Bob Proctor calls this The Law of Attraction. Bob Proctor quotes Andrew Carnegie to help illustrate this idea:
that is either feared or revered will, begin at once
to clothe itself in the most convenient
and appropriate physical forms available."
Whether or not you believe in this law, this book is highly motivational and inspiring. This book will discuss how to set goals, develop a winning attitude, and how to develop a personality that is conducive to getting what you want.
