Hmm... that's a rather large question - well, at least to me.

[she'll waddle around as she thinks about it before settling on - ]

I love it when people are happy, and this seemed like a job that would best allow me to be able to create those conditions. I think that school can be a very nerve-wracking place, full of social pressures and fears, so... I thought if I could be in charge of a dorm, I could help create a home for people.

There are also things like being able to live on campus, having it look good on a resume - but if I'm to be honest with myself, it's more for the first reason.
