If I only did things I enjoyed, I wouldn’t be able to live because I don’t enjoy most house work, cooking, shopping, plenty of necessary things at work (and I have changed work a few times to maximise what I do enjoy, but there’s limits), etc.

I do feel that a large reason why mundane, boring or unenjoyable things are so hard has to do with overstimulation from low effort high dopamine activities. It becomes much easier to tackle these things if your base level of dopamine is low, so small achievements give you a nice boost. It’s very hard to keep the base level low, though, in our always connected high stimulation world...
