Two things are infinite: the universe and human stupidity; and I'm not sure about the universe.

A friend is someone who knows all about you and still loves you.

In three words I can sum up everything I've learned about life. It goes on.

Success is not final, failure is not fatal: it is the courage to continue that counts.

Few people know what they mean when they say, "I love you." ... Well, what does the word love mean? It means total interest. I think the reason very few people really fall in love with anyone is they're not willing to pay the price. The price is you have to adjust yourself to them.

Try not to become a man of success but rather try to become a man of value.

You never know what life is like, until you have lived it.

It is not a lack of love, but a lack of friendship that makes unhappy marriages.

Without ambition one starts nothing. Without work one finishes nothing. The prize will not be sent to you. You have to win it.

Live as if you were to die tomorrow. Learn as if you were to live forever.
