If you enjoy the goal, but not the process, there's a term for it - it's called a grind. It's no different from weight loss or any other unpleasant chores. You choose to temporarily suffer in order to accomplish the goal. Incidentally, after reading a bunch of biographies, I think many high-achievers are into suffering, they get a kick out of it. Someone like Goggins makes it explicit, but I think it's fairly prevalent.
