自己
The only thing standing between you and your goal is the story you keep telling yourself.
The greatest investment you can make is in yourself.
I don’t compete with others, I compete with myself.
The best way to find yourself is to lose yourself in the pursuit of something greater.
The only person you should try to be better than is the person you were yesterday.
I don’t play for the crowd, I play for myself.
I don’t focus on what I’m up against, I focus on my goals.
I don’t want to be compared to anyone. I want to make my own history.
You have to believe in yourself when no one else does.
You have to believe in yourself when no one else does – that’s what makes you a winner.
The moment you doubt whether you can fly, you cease for ever to be able to do it.
"I believe in myself and my abilities."
"I love competition. I love to push myself."
"I work hard, and I do good, and I'm going to enjoy myself. I'm not going to let you restrict me."
I've never been a person that has been like, 'I want to be a role model.' But then you realize you are, and you have to be careful with what you say and do.
The day I stop believing I can win is the day I'll stop playing tennis.
You have to believe in yourself when no one else does.
The only limit is the one you set yourself.
The moment you doubt whether you can fly, you cease forever to be able to do it.
