You live during the match, and you have strong emotions, but you don't want to get too overexcited. My body's totally flat now. I cannot move anymore. I'm totally exhausted, just because of the tension out there.

For me, it's important that a fan can buy something that is related to me. Like in soccer, you buy a shirt and it's got somebody's name on the back. That's kind of a cool thing.

I definitely feel there's room for improvement.

The crowds are very important for tennis. It makes you play better, but it can also make you nervous and that's the beauty of it.

One of my big, big strengths I think early on in my career was that I could learn very quickly. You wouldn't have to tell me the things 10 times or 50 times until I would understand them. You would only have to tell me two or three times.

The one thing you can do for sure is push the luck on your side

I can walk around screaming, 'I have 17 Grand Slams. I have the record here or there.' When you can play for history and you do it, that's what is so really cool, is that you can then be compared to other greats or you've passed another great, even though it doesn't mean you're better than him. But it's just like that moment you've gone into the unknown where nobody else has ever been before.
