I guess I am a bit of a dilettante. I always have some new thing to be doing or trying to learn. Always a instrument I'd like to learn to play (guitar), a project I need to put together (longboard), some strange skill I'm working on acquiring (handstands).
I enjoy camping, hiking, canoing -- all kinds of outdoor things, even though I can't go very often. Recently I learned to skydive and when I was younger I learned to hang glide. I fully intend on picking both of these back up in the future. On that note, I suppose I am what some call an adrenaline junky. I just think I take calculated risks, the same as when other people get into a car.
I'd definitely rather be relaxing in the woods somewhere or cruising on a longboard than at a party, but I'm up for almost anything in moderation.
