I guess some kids around me had to grow up quickly, had all those problems. But I wasn't one of those kids, or around those kids, not at all.

It wasn't like I was self-motivated. My dad started me. It was his dream before it was mine.

I know I'm good at tennis. Other than that, everything else is a wild card. I'm a wild card.

Nerves are normal. You can't be cured from them unless you're a machine.

I think that Billie (Jean King) and Zina (Garrison), they have a whole lot of experience. Even if I don't quite agree with something or have a different way of doing it this week, whatever they said, I did it right away and I found out that it was correct. I think that's helped a lot...I'm having fun. I had a lot of fun out there. Sometimes I was ready to smile -- but I knew I'd lose focus -- because I was doing things that I'd done in practice and we talked about. I was ready to laugh and give someone a high-five, but it wasn't time for that.

Sometimes, when there's a video montage. I'm thinking, 'That's my life. Oh, my God, I did that.' Yeah, it's amazing.

There were a lot of people shouting out. I know it's not proper tennis etiquette, but this is the first time I've ever played here that the crowd has been behind me like that. Today I felt American, you know, for the first time at the U.S. Open. So I've waited my whole career to have this moment and here it is. ... It was great. It was awesome. It was like winning gold.
