Various freelance / project based work would probably come close. I know that jobs with short deadlines and big changes of focus have been manageable, while I’ve never lasted long with regular week after week of ongoing or repetitive tasks. Stuff like theatre / arts projects, or even some types of construction involves working really hard for a couple of weeks until something is achieved, and then doing something different.
My current job teaching at a university almost hits the sweet spot, because I only ever work six weeks before some sort of holiday, and there’s big vacations in between semesters. But coordiating the same class over a 12 week semester, even with a half term week off in the middle, is a big challenge to my willpower. About halfway through I start to check out and everything starts to fall apart.






It’s the case for all dishwashers I know about. It’s not that weird if you think about it. When people wash dishes by hand, they often wash a bunch of dishes in the same basin, with the water becoming increasingly dirty. Depending on how dirty and how much they care, they’ll change the water occasionally. Then they’ll give everything a rinse in clean water to get rid of soap. (obvs people do dishes on a variety of ways, but this is pretty common in western cultures.)
Dishwashers are the same, spray the same hot soapy water over the dishes for a while, until it’s dirty and most of the solids have been removed. Then drain and wash again with clean water. The soapy stage is about removing dirt, but the sanitising comes afterwards with the hot rinse and drying.
