I recently read a blurb about not having to do things well, and I agree that you do not have to be competitive for the activity to be worthwhile. That said, one should also endeavor to do things as well as possible when doing them - and if you are going to do something again and again, to strive to improve.

Imagine baking cakes every week, and doing it so poorly each time that neither you nor anyone else wants to eat them. Imagine being OK with that outcome, five years and zero improvement later.
