That's a question I really struggle to answer... I can't define myself, I'm only 18 years old, i've spent my entire life fairly sheltered from reality, going to good schools, living in nice places. I've always done very well for myself, achieving very high grades, but I never feel as if I've done myself justice. Hence I always drive myself on to achieve more, I'm always super-motivated, and get very competitive as a result. Whether it's a physics problem or doing the washing-up in a local hotel that I've been working in for almost 3 years, I always put everything I can into what I do.
On a social note, I don't think I do very well, I can't stand it when people believe something that is so obviously wrong, (Note: actual facts as opposed to religious beliefs, on that front I'm both open-minded and undecided). I can be the centre of attention at a party but because I'm flamboyant more than because people like me. I find it easier to talk to girls than boys, but dread meeting new people... I'm going to university in 10 days and am terrified. However I'm also really looking forward to being around like-minded people and studying physics at one of the best universities in the world.
I'm very much a creature of habit, and just spent half an hour writing my first post in an awful long time simply because I missed The Escapist and the time passed just browsing the forums, I also follow xkcd, Penny Arcade, and Cyanide and Happiness avidly, despite not being too keen on the latter, I just feel like I have to. I also have to tap my heels on the vertical part of steps as I walk down steps. Things like that make me quite socially awkward and I often feel quite alienated, this was worse in the past but I've made some really close friends in the last 2 years after being a really horrible person previously, and have spent the last 20 months in a relationship with an amazing, wonderful, beautiful girl. =)
Also, I reeeeeally like biscuits. =)
