Tennis was always sort of a - a learning. It was a vehicle for me to discover a lot about myself. And the things that I sort of discovered at times I not only didn't want to see it for myself but I certainly didn't want millions of people to see it.

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

People who are interested with me have for sure gotten older over the years, for example, grandparents are coming up to me telling me they grew up watching me.

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.

I always felt tennis and winning was a byproduct of doing everything right.

If I've learned nothing else, it's that time and practice equal achievement.

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.
