Life is either a great adventure or nothing.

The basic fact about human existence is not that it is a tragedy, but that it is a bore. It is not so much a war as an endless standing in line.

Believe that life is worth living and your belief will help create the fact.

With the past, I have nothing to do nor with the future. I live now.

All life is an experiment. The more experiments you make the better.

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

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

I always like to look on the optimistic side of life, but I am realistic enough to know that life is a complex matter.

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.

Every man dies. Not every man really lives.
