Some people say I have attitude - maybe I do... but I think you have to. You have to believe in yourself when no one else does - that makes you a winner right there.
I don't focus on what I'm up against. I focus on my goals and I try to ignore the rest.
Just believe in yourself. Even if you don't, pretend that you do and, at some point, you will.
My motto is: I'm alive, so that means I can do anything.
It's easy to stand back, but to move forward and take a chance, that takes a little more guts, a little more courage.
So what if you fail? At least you'll know what not to do when you try again.
In my mind, I'm always the best. If I walk out on the court (and) I think the next person is better, I've already lost.
Life is challenging but I'm always up for a challenge.
Losses have propelled me to even bigger places, so I understand the importance of losing. You can never get complacent because a loss is always around the corner. It's in any game that you're in - a business game or whatever - you can't get complacent.
I don't have time to be negative.
Of course, I want to be number one. But being happy and healthy is the most important thing.
If I cared deeply about what people thought of me, I probably would have never made it out of Compton, California.
When you lose, you're more motivated. When you win, you fail to see your mistakes and probably no one can tell you anything.
Tennis is mostly mental. Of course, you must have a lot of physical skill, but you can't play tennis well and not be a good thinker. You win or lose the match before you even go out there.
Just always believe in yourself. "Champions adjust." It's a line I learned from Billie Jean King, and sometimes your dream adjusts. Be willing to adjust with it and see where your opportunities ... sometimes a door closes but a window opens, so just follow your dreams and continue. You never know where it's going to take you.
In the sports arena I would say there is nothing like training and preparation. You have to train your mind as much as your body.
It's amazing when tragedy strikes, how strong you find that you are, and I'd seen other people go through horrible things. And I just thought, "Wow, I would be a complete mess," and then suddenly when it happens, you realize you had more strength than you knew and it helps you to get through.
You can never get complacent because a loss is always around the corner.
I am someone who likes to stay positive.
My first job is big sister and I take that very seriously.
Everybody's got their problems. The important thing is not to complain about it.
The naysayers, they don't mean a thing.
Workout. Lead a balanced life and try to have fun. It's what you make it.
My goal is always the same: to keep the other player from ever scoring a point. That doesn't always happen, but that's what I try for.
Nerves are normal. You can't be cured from them unless you're a machine.
