It reveals my age, but my first job was working at a video rental store in a little town. It was one of only two, so I managed to at least half of everyone.
Turned out to be a great experience, immediately exemplified my work ethic, and I managed to become a lot less shy having to work with the public.
I find it's worth it to learn from every job, crappy or not. I've worked my way through everything I've done, held at least two jobs for over ten years at one point, and now find myself doing something that I truly love, with a lot of fantastic professionals.
OP, congrats on the first job. You'll find that doing everything that is asked of you, and the first time it is asked of you, will usually exceed expectations, because /so/ many people fall below expectations in entry level positions like that. Standing out is how to get ahead, even if it's just by a nose.
