Computers, science in general. Been a science nerd since day one.
I've always had a natural musical aptitude, and have had classical piano lessons since 3rd grade and choir since 5th.
For some reason I can absorb most books like water. Once I read them once I'll remember specifics down to direct quotes years later.
I'm pretty athletic. I played house league soccer for 8 years, love cycling and Krav Maga.
Camping, backpacking and such.
Other than that I can do well at anything I put my mind to, and I've got a long list of things I intend to teach myself (ie: rock climbing fancier cooking, astronomy, new programming languages, advanced car maintenance, etc) The one exception so far is art. Maybe it's just due to my lack of interest (at least into the "analysis" stuff), but even when I put serious effort into learning how to draw (stuff that actually looks good) the only way I can really get anything accomplished is trial-erase. Guess I'm just not wired for it.
I'd also like to think I'm a good person. I'm constantly trying to improve myself and I see no reason to stop.
