I think there's two branches:

1) Things you do because you love doing them. Like spending time with your kids - it's not about doing it as-best-as-is-possible, it's just about doing it because you love doing it. It's worth doing for you, so you don't have to worry about how well you do it.

2) Things that are outcome-based. When it doesn't matter if you're the right person for the job because you're the ONLY person for the job and the job needs doing.
