I went through a numer of books at the end of grad school. It was a pretty crappy time in my life, and I was just looking for a way to get through the next day. "Zen and the Art of Motorcycle Maintenance" was the one that really changed my life. I thought it was so cool the main character was getting his PhD in Rhetoric. I had no idea one could get a degree in that, much less a PhD. Well, it turns out I met a woman a few weeks that had a PhD in Rhetoric! I took that as a cosmic sign and asked ne to marry me on our first date. Nine years and five kids later, I still don't know what one does to get a degree in rhetoric....
