At the end of the day, you just have to focus on winning. No one can take a win away from you. That's what I focused on. Life is not fair, so I don't go out there expecting it to be. I don't think any of us should go out expecting life to be fair. I think that's expecting too much, and I remind myself of that sometimes. You can get on with your life after that.

To be a well-rounded person and know what's going on in the world around you, to have a perspective outside of your sport, is important for every athlete. I'm blessed that our parents gave us that.

It's amazing when tragedy strikes, how strong you find that you are, and I'd seen other people go through horrible things. And I just thought, "Wow, I would be a complete mess," and then suddenly when it happens, you realize you had more strength than you knew and it helps you to get through.

Tennis is mostly mental. You win or lose the match before you even go out there.

I think business is the same as tennis. You have to have the love, that helps, or else it's just too much pressure to be able to keep up with.

I'm only seeing tennis balls these days. And maybe the occasional fashion sketch.

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.
