Query: A Must Read

You must read this book if you are interested in any type of self-improvement, personal development, or understanding of yourself and others. After reading the first chapter, I was going to buy a highlighter to start highlighting the important sentences in each chapter. I am glad I didn't. The entire book would be highlighted. Every sentence put me deeper and deeper into the understanding of myself and the world around me. I have read several best selling "self-improvement" type books and none came close to the affect this one had on me. This book should be read by everyone. It helped me understand my attitudes towards myself and others and what to do to correct and/or improve on them. I can't say enough about the book, except buy it! You will thank me.
