I'm in my fifties, I'm an academic and I've plateaued. I am bored with the courses I teach, the students I teach, and the responsibilities I have. The only way to move up is to take another job elsewhere, but we're a two career family, and our kids are in college and need the tuition waiver. My husband feels similarly plateaud in his govt job. I think maybe this is typical -- you get sort of stuck. It's impossible to move, and you find yourself counting down to retirement. Kind of the way the kids become really annoying in their teens so you're glad to see them go to college. Your job becomes shitty so you look forward to retirement. Sorry to be so cynical. I'm at a conference and I've been drinking.
