No pessimist ever discovered the secret of the stars, or sailed to an uncharted land, or opened a new doorway for the human spirit.

There is no blindness more insidious, more fatal that this race for profit.

What really counts in life is the quiet meeting of every difficulty with the determination to get out of it all the good there is.

So long as the memory of certain beloved friends lives in my heart, I shall say that life is good.

The highest thinkers of the ages, the seers of the tribes and the nations, have been optimists.

No pessimist ever discovered the secret of the stars, or sailed to an uncharted land, or opened a new doorway for the human spirit.

No matter how dull, or how mean, or how wise a man is, he feels that happiness is his indisputable right.
