I'm always on the court with my dad.

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.

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.

Of course, I want to be number one. But being happy and healthy is the most important thing.

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.

When you lose, you're more motivated. When you win, you fail to see your mistakes and probably no one can tell you anything.

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.

...no woman can love a weak man hard enough to make him strong.

To master life, control the mind. To control the mind, guard your speech.

It is hard to imagine a more stupid or more dangerous way of making decisions than by putting those decisions in the hands of people who pay no price for being wrong.

Growing up, coming to terms with, and living through the complications of Diabetes.

A scientist who is also a human being cannot rest while knowledge which might be used to reduce suffering rests on the shelf.

I think it was when I was nineteen, by that time the Jewish laws were already in force and the split was beginning to come about which isolated the Jewish culture.

I'm dreaming of a white Christmas, just like the ones I used to know.

There is a sort of economy in Providence that one shall excel where another is defective, in order to make men more useful to each other, and mix them in society.

There's nothing like the force and challenge of a new ballet to galvanize everyone involved in bringing it to life.

Form and content must never apologize for each other.
