Man, I was actually hoping for a majority of serious answers out of this thread. I suppose, given my latest outlook, that my answer should be "being less elitist."
My actual answer is writing. I have it as a hobby right now, and I've done it once professionally (on this site), but it's something I'd love to do for the rest of my life given the opportunity. So, getting better at it is something I really want to do both in the short and long term. Maybe gaining contacts in the business as well, since that could help me get published. But mostly writing, it's a hobby I both enjoy and think I could do professionally given enough practice.
