“Burnout” was first recognized as a psychological diagnosis in 1974, applied by the psychologist Herbert Freudenberger to cases of physical or mental collapse as the result of overwork.1 Burnout is of a substantively different category than “exhaustion,” although the two conditions are related. Exhaustion means going to the point where you can’t go any further; burnout means reaching that point and pushing yourself to keep going, whether for days or weeks or years.
