I am not promoting what happened to an acquaintance of mine who worked as an accountant for years and found he was a square peg in a round hole and not only hated the years he worked, but the weeks, the days, the hours and probably even the minutes. He took on a much less stressful (and better working hours) job (clerical officer, public service) with a massive earnings drop. Remarkably, he never sought promotion through internal competition.
Almost immediately, he stopped his excessive drinking, became a much happier and content person and saved himself from a long stay mental hospital.
