Currently I'm a peer mentor for our freshman engineering program. I have a group of students that I meet with individually once a week just to make sure everything's going well with their college experience and to give advice if they're having any kind of trouble with classes, homesickness, dorm life, etc.
For the most part we just sit around and talk about whatever, though sometimes I do have some more serious stuff to deal with. I enjoy my job pretty well.

I'm studying computer science because I'm good at programming and could see myself doing it for at least a while. My big dreams include making video games, writing/directing movies and opening up my own tabletop gaming shop. The one I want the most is probably the least feasible (movies)
