When I hear this question I always think back to the interview I had at a job at the Jet Propulsion Laboratory in Pasadena, CA. It paid about 2/3rds of what I thought I was worth and the guy interviewing me talked me out of it. It was a calibrationist where I would be making sure all the equipment met standards like weight and other dimensions.
But I think even though we make one decision against what we think would be a good choice, eventually we settle into what we are capable of given the opportunity. Opportunities eventually came my way so that I was able to have a successful career.
