你
"You have to believe in yourself when no one else does."
"The biggest weapon on the court is not your forehand or backhand—it's your mind."
"If you want to be the best, you have to beat the best."
"The more you give, the more you receive."
"I think the mind is the most important thing in any sport. If you can control your mind, you can control the situation."
I’m not a player who’s going to dunk on you and talk trash. I’m going to dunk on you and run back on defense.
I like criticism. It makes you strong.
You have to be able to accept failure to get better.
Dreams are made possible if you try.
It’s not how you fall, it’s how you get back up.
I think goals should never be easy, they should force you to work, even if they are uncomfortable at the time.
You can’t put a limit on anything. The more you dream, the farther you get.
"You have to believe in yourself when no one else does—that makes you a winner right there."
"Pressure is a privilege—it means you have an opportunity to do something great."
"The more you win, the more you want to win."
"The more you sweat in practice, the less you bleed in battle."
"You have to be ready to suffer and enjoy the suffering."
I don’t think you should ever feel like you’ve achieved everything. You always have to keep pushing.
When you do something best in life, you don’t really want to give that up – and for me it’s tennis.
Tennis is a brutal sport. There are no draws. If you lose, you’re out.
