I ended up migrating to fixing things in the libraries I use because they piss me off.

Bad onboarding docs, broken or bent SDLC, major performance issues. I spent all day yesterday fixing perf issues in a library that competes with one I loathe for trying to complect an entire problem domain.

You probably have the same thing I do. Teamwork is a very different motivation than working on something either never intended for others or with a long MVP cycle that makes it too easy to get bogged down with side quests. "It would be way less tedious to deal with X if I did Y first. But now Y is blocked so I do nothing."

Versus 'someone is waiting for this.'
