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.

I love to be busy, and when I'm off the court, I do things I love.

If I cared deeply about what people thought of me, I probably would have never made it out of Compton, California.

The thing about tennis is if you stay off for two weeks, or just for three days, you can lose your rhythm quickly. So it's just a question of constant diligence and vigilance.

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.

So what if you fail? At least you'll know what not to do when you try again.

I just try to stay positive and focused on the tennis, not let anything get to me, like crazy questions. But I'm tough, let me tell you, tough as nails.
