there is a book called Purpose Driven Life by Rick Warren, very interesting book I must say. Some is a bit nonsense to my believe but lots is make sense too. so go check it out.. here is the link http://www.purposedrivenlife.com/en-US/Home/home.htm this book is for Christian but my personal opinion is good for everbody. I think he was here one year ago to give speech to his fans/follower.

Everybody is right Everybody is wrong, it depend where we stand.
