You can't measure success if you have never failed.
It's so difficult to find time besides the tennis.
You can have a certain arrogance, and I think that's fine, but what you should never lose is the respect for the others.
Age, what is it? It's not a figure that has ever meant anything to me.
When you lose a couple of times, it makes you realize how difficult it is to win.
