In tennis you're on an island. Of all the games men and women play, tennis is the closest to solitary confinement.

Tennis uses the language of life. Advantage, service, fault, break, love - the basic elements of tennis are those of everyday existence, because every match is a life in miniature.

If you don't practice you don't deserve to win.

Sometimes it's just harder to remind yourself about what you're doing and why you're doing it... Other times, you have a great desire for it, but physically you're not responding the way you want. That presents other challenges. Then sometimes it all comes together.

A strong body listens. It obeys. A weak body commands. If your body is weak it tells you what to do. If your body is strong it'll actually listen to you when you tell it to do something. If you build it right you can overcome some of the obstacles of age and recovery.

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.

When I was 7 years old I saw Jimmy Connors make someone carry his bag, as though he were Julius Caesar. I vowed then and there that I would always carry my own.
