This is similar to Type 2 fun that is part of the popular "Fun Scale" (https://www.rei.com/blog/climb/fun-scale) idea in backcountry activities: Type 1 fun is an activity that is enjoyable while it is happening (eating, drinking, sex, etc.). Type 2 fun is not only not fun while it happens, it's miserable (freezing all night in a tent, being hungry for days on end, fearing for you life, etc.) - but in retrospect the experience creates a great deal of happiness, satisfaction, and a desire to do it again.
