Will I have to explain to my daughter that her brother is gonna make more money doing the exact same job because he's a man? If they both played sports since they were three years old, they both worked just as hard, but because he's a boy, they're gonna give him more money? Like, how am I gonna explain that to her? In tennis we've had great pioneers that paved the way - including Venus [Williams], who fought so hard for Wimbledon to pay women the same prize money they pay men, and Billie Jean King, who is one of the main reasons Title IX exists.

All I want is to have fun in what I'm doing every day. I don't want to break records. To become the greatest player ever could take me like...10 more years and I don't think I'll still be playing at 31.

There's always another record, then there's always another person to catch up with or to pass.

Everybody who plays me plays me so hard because they always want to beat me.

We're going in really fresh. We're going to have fresh legs and bodies, we're going to be able to stay the distance, and that's our goal.

I never close my mind to anything and eventually want to branch out. But for now, tennis is still number one for me.

If you smile things will work out.
