Here's a list of ways to be a superstar at work, from GL Hoffman. It applies equally to a 19 year old close to me who's starting her first full time job, or to developers who want to work for me. The examples in the article are aimed at a 20-something working in an office full of older people, in a vaguely technical capacity, and is kinda Web 2.0 ish, but the principles are far broader than that. My two favourites: See Work and On Time. But read them all.
