The Purpose Driven Life is one of those "once a year" books. The teaching is timeless and the exercises are refreshing. The more you read it, the more you'll be able to define your life's purpose and put steps in front of you to accomplish that purpose. I can't say enough good things about it. For anyone reading it for the first time, I encourage you to take your time, digest the material, and work through the exercises as Pastor Warren recommends.
