I played pretty well in my twenties, don't get me wrong! But my consistency is better [in my thirties], my momentum is better, my wins are quicker.

If anything, we haven't changed much since we [with Venuse Williams] were kids. We really are the same people.

If Plan A isn't working, I have Plan B, Plan C, and even Plan D.

If I'm winning, I have to act like I'm not bored. If it's A tough match, I have to act like I'm having A good time. I'm a drama queen.

I think in life you should work on yourself until the day you die.

I don't have anything to prove ever, ever in my life. If I have something to prove, what does that mean for everyone else? And I think everyone should have that attitude. You just have to prove to yourself that you can go out there and be the best that you can be and not prove anything to anyone.

I'm an unbelievable designer. I don't know how I know and just do these things. I just start sketching and then I just know the colors and I always know the forecast. I know green and purple are going to be hot. I was born to be a designer. I worked hard to be a tennis player, I don't work hard to be a designer.
