One thing that I find people generally lacking is some good old fashioned fun, I always try to keep the kid in me alive and kicking; "When I became a man I put away childish things, including the fear of childishness and the desire to be very grown up"-C.S. Lewis. I love making people laugh and I will always be down with going out and doing something I've never tried before. To me, good company and good booze will always make a fantastic time.
I love things that have to do with water and a board: snowboarding, surfing, wakeboarding, water boarding, etc.
I proudly and shamelessly wave my nerd flag: Whether its spouting pop culture references, playing some video games, watching sci-fi or you name it, I'm always down for it.
INTP for those of you who keep track of such things.
