Purpose

Purpose and fulfilment sort of get wrongfully intertwined. Just do what you want to do all the time
If you want to stick to something great
If you don't, also great
Do you want to be good
Do you want to be great
Do you want to be elite
Do you want to be mediocre
It only matters in relation to what you want whichever one you pick is just as good as the others as long as your honest with yourself about it
