Doing your best isn’t about the result. You know you did your best before you know the result. Doing your best is about the position you find yourself in when you show up. Over the long term, the average person who constantly puts themselves in a good position beats the genius who finds themselves in a poor position.
From Doing your Best.
I really like this paragraph and it reminds of this one from Seneca:
Luck is what happens when preparation meets opportunity.
