I think one of the greatest joys in my life is learning something new or some new/different facet of something I thought I knew or already understood. Maybe it's why I went into a profession based around information. Hell, I know it's why I did that.

I think I'd be insanely depressed if I didn't have the opportunity to learn something new every day. My parents are very much of the "well, I don't want to learn how this/that new thing works" or "I don't see the point in reading" and it's so opposite me. I thrive on adding to my knowledge base and evolving as a person.
