Good question. I guess I was kinda giving up on the idea even before I started doubting the veracity of Christianity. So it had to be something else.....

I've always been interested in so many things that I could never settle on any single profession. I think I switched my college major a dozen times. My 20's was just a mess. No direction. But.... I never stopped learning, reading new things and experiencing new things. So, I don't regret the "mess". Maybe that's exactly what a young person should do.... experience and learn as much as possible instead of focusing on a single discipline.

Eventually, it was reading a few key books that made me turn from Christianity entirely.
