I think it's natural to want to move "up," but UP means different things to differnet people. Preferring to be an individual contributor will naturally have an organizational boundry, but that doesn't mean ambition halts. I am always hungry to explore, learn, do more, but I don't have a strong desire to be a full-time people leader.
Lately I've been trying to figure out what ambition means to me. I don't consider myself a super ambitious person. Does a person who isn't ambitious still have a place in the work world? If so, what is it? If I don't consider myself ambitious, then what are my motivations for working?
Big questions I'm trying to answer for myself. A work in progress!
