It is possible that you eventually decide that the fact that you didn’t get promoted is no problem at all. Being passed over may give you more time to spend at home, to learn something new, to devote your psychic energy to some other task. You may come to realize that the problem was your competitiveness, your ambition, the fact that you invested all your energies in advancing on the job rather than doing a good job for its own sake, or living more fully. So the failed promotion, instead of being the problem, is really the first step to the solution of a more fundamental problem.
