Query: A great prequel that explains Millman's inspirations.

What a fantastic book. I knew it would be good, but I didn't know it would be this good. I read Way of the Peaceful Warrior when I was a freshman in college during some tough times. Just like they did with me, I passed that book to a friend who seemed to be ready for a change in his life. Millman is a master at explaining how we can change our daily lives in an entertaining yet not ridiculous manner. So many books that are considered "metaphysical" just lay out the answers in front of you and make you believe that these are the answers, Millman writes it in a manner where you have to decide what best works for you. The book is a further discovery in how a person deals with their most powerful demons and ends up coming out on top. The last few pages were the greatest eye opener into Millman's soul and his journey through life. Definitely the best one of all of the books he has written.
