At a career management course for HBS alumni, I learned that a person typically gets sick of a job after 18 months. This is a natural cycle, as you go through the excitement of learning a new job, become expert at it, and then gradually, it gets routine. So the advice I got was to plan for job obsolescence every 18 months. This didn’t mean that I had to leave the company and go to a new place – it had more to do with redefining my current job first to incorporate new challenges.
Nach 18 Monaten schon? Erscheint mir schnell. Aber nun gut, hat auf jeden Fall was.
