Open your eyes, look within. Are you satisfied with the life you're living?

One of the secrets of life is that all that is really worth the doing is what we do for others.

Not life, but good life, is to be chiefly valued.

Good friends, good books and a sleepy conscience: this is the ideal life.

Don't go around saying the world owes you a living. The world owes you nothing. It was here first.

A chief event of life is the day in which we have encountered a mind that startled us.

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

The happiness of this life depends less on what befalls you than the way in which you take it.

Once you say you're going to settle for second, that's what happens to you in life.

A man who dares to waste one hour of time has not discovered the value of life.
