I had so many outs in my career. I could have said, I don’t need this. I have money; I have fame; I have victories; I have Grand Slams. But when your love for something is bigger than all those things, you continue to keep getting up in the morning when it’s freezing outside, when you know that it can be the most difficult day, when nothing is working, when you feel like the belief sometimes isn’t there from the outside world, and you seem so small. But you can achieve great things when you don’t listen to all those things.

Ever since I was young I loved making things and being part of the design process.

It'll be great. Of course I was disappointed last year. But . . I'll get my revenge.

Sometimes when you're putting the work in it just seems so, so hard, and you never know when that work's going to pay off.

To be honest, everything in my life outside of tennis is great. I'm doing amazing projects that, if I didn't have time off, I wouldn't be able to focus on.

I heard endless conversations between my parents when I was going to sleep about how we would survive, how we would continue. All of them were about trying to make me better.

If everything was going smoothly you would never build character.
