Frunobulax has raised an interesting issue here and one which has more questions than answers I suspect.
My own experience (after 34 years in ATC) is that change is good for me, if I stay too long in one place/job/skill then I become a little complacent and less interested in being involved.
I then transfer to another job/place/skill and the whole process of being interested and involved starts again.
I can take the experience I've gained in previous jobs and use them to my (and the company's) advantage to hopefully add to the overall skill base of the team I'm working with.
This might not work for everyone but I feel it's kept me sharper and maximised what potential I've got.
Others may have there own ways of measuring themselves, I'd love to hear them..........
Sorry spelling error..."There" should be "their"
