The wise man seeks death all his life, and for this reason death is not terrifying to him.

Life is full of questions. Idiots are full of answers.

What screws us up the most in life is the picture in our heads of what it’s supposed to be.

True wisdom comes to each of us when we realize how little we understand about life, ourselves, and the world around us.

I gave my life to become the person I am right now. Was it worth it?

Here is the test to find whether your mission on Earth is finished: if you're alive, it isn't.

Have you ever asked yourselves what you are going to do when you grow up? In all likelihood you will get married, and before you know where you are, you will be mothers and fathers; and you will then be tied to a job, or to the kitchen, in which you will gradually wither away. Is that all that your life is going to be?

Maybe it's true that life begins at fifty. But everything else starts to wear out, fall out, or spread out.

You must understand the whole of life, not just one little part of it. That is why you must read, that is why you must look at the skies, that is why you must sing and dance, and write poems and suffer and understand, for all that is life.

Focusing your life solely on making a buck shows a certain poverty of ambition. It asks too little of yourself. Because it's only when you hitch your wagon to something larger than yourself that you realize your true potential.

Each player must accept the cards life deals him or her: but once they are in hand, he or she alone must decide how to play the cards in order to win the game.

I have frequently been questioned, especially by women, of how I could reconcile family life with a scientific career. Well, it has not been easy.

Life is not easy for any of us. But what of that? We must have perseverance and above all confidence in ourselves. We must believe that we are gifted for something and that this thing must be attained.

Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less.

I was always very interested in science, and I knew that for me, science was a better long-term career than tennis. So I decided on science when I was in college.

I suggest taking a high road and a little sense of humor and let things roll off your back. I think that's very important.

The fact that I was going to be the first American woman to go into space carried huge expectations along with it.

When you’re getting ready to launch into space, you’re sitting on a big explosion just waiting to happen.

Step with care and great tact, and remember that Life's a Great Balancing Act.

The greatest moments in life are not concerned with selfish achievements but rather with the things we do for the people we love and esteem.
