I look back on my life like a good day's work, it was done and I am satisfied with it.

The only real failure in life is not to be true to the best one knows.

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

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

A life spent making mistakes is not only more honorable, but more useful than a life spent doing nothing.

Life is what happens while you are busy making other plans.

The good life is one inspired by love and guided by knowledge.

A healthful hunger for a great idea is the beauty and blessedness of life.

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

Life is a dream for the wise, a game for the fool, a comedy for the rich, a tragedy for the poor.
