Is your current job both demanding and in your control? The most fulfilling jobs share a common trait: They prod us to work at our highest level but in a way that we, not someone else, control. Jobs that are demanding but don’t offer autonomy burn us out. Jobs that offer autonomy but little challenge bore us. (And jobs that are neither demanding nor in our control are the worst of all.) If your job doesn’t provide both challenge and autonomy, and there’s nothing you can do to make things better, consider a move.
