I feel such gratitude to know that there are things I am good at & enjoy that serve an important purpose. It doesn't need to be the *most* important. There is no "most important".
There are just things that need doing & people to do them. They say "if a thing is worth doing, it's worth doing well," & that's true enough, but we can start with: if a thing is worth doing, it's worth doing.
Find useful shit to do & do it. It does not need to be the most "important" & world-shaking.
