If I didn't play tennis I don't know where I'd be.

I don't focus on what I'm up against. I focus on my goals and I try to ignore the rest.

Most definitely always been a passion, and always been one of my goals in life as a young person, to have my own business. My dad gave us his entrepreneurial mindset, so that was also ingrained, as well as the tennis. So in a lot of ways it's a part of making my parents proud. I think we all want to make our parents proud, you know?

A win's a win, unless it is not a win, and then it's not a win.

Rain is good for me. I feel like I achieve clarity actually when it rains. The longer I have to sit and wait, the clearer my game becomes to me.

I think there's more stressful periods than others when you're launching new things or going into a new business, or there are many things that can stress you out. Having to let people go, that's stressful. Never fun. But for the most part, I try to manage a schedule that's achievable and try not to make a schedule that's not. And a lot of times, sometimes it becomes a little unmanageable, but in spurts. So I think being able to make an achievable schedule, one that I know I can accomplish.

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.
