When I'm playing my best, like I was at the U. S. Open, I feel on top of the match and able to do exactly what I want. There are other times when you're not in control, but that is tennis and you have momentum changes in every single match.
You are here and you are allowed to be here and therefore you are allowed to make decisions about yourself and the people in your life; rather than sort of backing up and making sure it's okay with everybody at every turn.
