To me, much of what you describe sounds like the nature of creative work. Painters sketch, bands rehearse, athletes practice, and there is no academy award for fewest takes in a feature film.

Creative work is enjoyed by embracing the messy process. Frustrations and all. Only assembly lines are repetitive and solving hard problems feels like hard work because it is.

The good side of creative work is it is mostly not boring. Therefore you don’t have to make up high standards to have something interesting to do.

Do whatever it is that will make you the kind of person other people want to work with again. That’s what being on a team is all about.

Hard work feels like work. And it feels hard. Good luck.
