I enjoy a mix of different things, some of which include:
Music (both listening and playing)
Reading, writing, art/design
Sport (ie snowboarding, football, soccer)
Phylosophy and any thought provoking theories
And above all I just try to enjoy myself day to day

I've never really been able to answer this well because if I knew what I was looking for I would have found them...
But a couple of MUSTs in a person for me would be humour; someone who can make me smile and whome I can do the same for
And intelligence; someone I can really talk to about alot of things and not just the latest clothing sale thats on...
