I don't ever look back. I look forward.
I never hanker after the past - I prefer to devote myself to new tasks.
As long as I can focus on enjoying what I'm doing, having fun, I know I'll play well.
The tennis wasn't really very much on my mind, so it wasn't like I was thinking about it all the time.
You can't measure success if you have never failed. My father has taught me that if you really do want to reach your goals, you can't spend any time worrying about whether you're going to win or lose. Focus only on getting better.
Age, what is it? It's not a figure that has ever meant anything to me.
