I most certainly believe that when you're an athlete, that really translates to all sports. You just understand it, your body understands it, and your mind understands it. And you just - it just clicks. I've found that happening when I play other sports. I've seen it, like when I've hit the ball with other professional athletes, and you can see they're just learning so quickly. It's just something that's in their blood. So I think it was in my parents' blood and they understood.

Losses have propelled me to even bigger places, so I understand the importance of losing. You can never get complacent because a loss is always around the corner. It's in any game that you're in - a business game or whatever - you can't get complacent.

My parents always told us, you know, you have to get your education. You're not supposed to become a statistic.

The naysayers, they don't mean a thing.

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.

My ambition is to enjoy my life and to do exactly what I want to do. And I'll do that. I will be free.

I have a lot of dreams, and most of them come true these days.
