There's a lot of good waiting for you on the other side of tired. Get yourself tired.

Life will throw everything but the kitchen sink in your path, and then it will throw the kitchen sink. It's your job to avoid the obstacles. If you let them stop you or distract you, you're not doing your job, and failing to do your job will cause regrets that paralyze you more than a bad back.

It's shocking how little there is to do with tennis when you're just thinking about nothing except winning every point.

I don't always choose to stay fit by playing tennis, because that comes with its own wear-and-tear.

I think one of the greatest joys I have now in my career and in my profession is to be playing at an age where I can appreciate it more than I used to... It's a whole different lens you look through the older you get.

Tennis is one of the only sports in America where the sport doesn't grow with the size of the person - it just forces you to swallow the whole pill.
