I'm definitely not at my best. Honestly, I'm under 50 percent. But I've won stuff under 50 percent before.

I've developed a karaoke habit. I've become a crooner.

Tennis is my job, but it's not my life.

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.

When I'm 32? Hopefully I'll have made my mark with a few different movies, some scary ones and some comedies. I'm really funny, I have a great personality on the camera.

When I first started really playing, in '98, I was super excited to see all the people I grew up watching. ... I loved Monica Seles, Steffi Graf, and Pete Sampras.

I've always considered myself the best and the top. I never considered that I was out of it.
