I want to learn, as much as possible. I want challenging work. Because challenging work motivates me.
I want my supervisor to understand that I didn't apply for this job to do data entry for her (if that's why you hired me, you should've said so in your job description. Why did you lie during the interview?).
As much as I want to sharpen my technical skills (I know you probably don't agree with it, but my technical skills are superior than yours on most occasions - although I recognize that you probably know some things that I don't), I also want to work on my soft skills, e.g. I was amazed by how my supervisor deal with clients under a lot of stress.
It helps if you have a good personality so that I can respect you. Also, don't take a week off when the team is swamped with work.
