Dan Millman's book, Life you were Born to Live, is an interesting guide to discovering more of your possible paths in life. By using his numerological system you are led to the corresponding life year information for your self. I was surprised to see how "on target" it was with my hopes, dreams, and secret desires. This is a great book to help you understand other folks in your life. I looked up the birth /life path info on my parents, my sister, and some of my friends. It was really insightful and they found it intriguing too. It's a fun tool.
