Even sleep is part of my job because I need a certain number of hours of sleep to be able to train at the intensity that I do. I'm constantly working to keep my body in the best possible shape.

I'm very hard on myself. Sometimes too hard on myself. When I lost in the Wimbledon finals, I was so sad, I cried. I had the runner-up trophy! It's still a great accomplishment, but I was so mad.

After they lose, I think all tennis players go back to a specific part of the match where they wish they had done something different.

If you're playing someone you care about, it's tough, and I don't want to be in that situation. We are playing big matches for big points and prize money, and I take it very seriously. I relax when I'm outside tennis.

To really be conscious of how long the journey is, be patient, push yourself, persevere, and always be working on your craft while waiting for your break. That's what I'm still working on, having done this for 20 years now.

I know I'm never going to be as successful as my dad, but I get bored doing nothing. I couldn't go from vacation to vacation and have no motivation.

I can’t believe people love my music. It just feels like a dream because that is all I ever wanted.

Don't try to change anybody. And they should let you be yourself, 'You loved me when you met me, so let's keep going!'
