What's my purpose?

Last week I started reading Rick Warren's "The Purpose Driven Life". Has anyone else read it? The idea is that, as part of what's called the "40 Days of Purpose Campaign", you're only supposed to read a short chapter each day (obviously for 40 days). The 40-day "spiritual journey" (as it's called by the author) is supposed to help you figure out your purpose in life. So far I'm really enjoying it. I don't necessarily agree with his perspective on everything, which is probably because he is a Baptist minister and I was raised Lutheran and there are some differences in our approach to life. But nonetheless, it's thought-provoking and it does offer some interesting insight. Stay tuned.
