Sports for me is when a guy walks off the court, and you really can't tell whether he won or lost, when he carries himself with pride either way.

Tennis is still very successful in spite of itself.

When you lack cohesion, it becomes difficult to have a clear marketing strategy.

You have to be extreme to be exceptional. I couldn't revel in being number one. I had to get to zero. When my fitness was at its peak, I was intimidating. I made guys cave in. They'd be dejected in the locker room after matches, and I'd go out for a run, as if it wasn't enough. I'd rub it in their faces. I meant to do that.

Fear is an interesting energy that we all have to face. Some people step up and aren't afraid but still come up short. And some would rather cop out: "My shoulder hurts" or "I didn't give it my all." They can sleep at night.

I've been lucky enough to primarily work for myself over the years.

You can drill down on where hunger comes from and figure it out from there, but there absolutely has to be a sense of urgency if you're going to play tennis because you're the team - there's no one for you to rely on but yourself.
