I found this link I urge you not to miss on A Texan Abroad.
I've been doing a lot of thinking about what's really important in my life lately. That's probably becuase I've been reading A Purpose-Driven Life. I really can't describe the book, except to say that it focuses on helping you to find the core of your belief system, and re-build your life on that. It is a Christian-focused book, fair warning, but it is compatible with any denomination, including Catholicism.
