Hehehe, I didn't realize we were the same age--well going to be the same age in 3 days. And I understand what you mean. I got an internship at an ad agency this past summer and it was nice to be around folk who enjoyed what they did even though they were in a hurry all the time.
Dude, I'm already feeling old, for some reason my hips and back get all stiff. I think it's because I did way to much sitting during my drawing marathon in summer and never really recovered, plus school. If you don't stay in your seat in the library it's gone. I try to stretch more and that helps, but feel all crickety in the morning--like a transformer--clickety-crack-crack when I wake up.
Thankfully I have been able to have some really great instructors, the fact they really appear to like what they do really energizes me. I will make the best of it.
