"It often takes more courage to change one's opinion than to stick to it" — Georg Christoph Lichtenberg

Don't take the wrong side of an argument just because your opponent has taken the right side.

There is but one cause of human failure. And that is man's lack of faith in his true Self.

Great works are performed, not by strength, but by perseverance

Happiness depends upon ourselves

A man who won't die for something is not fit to live

Make it a rule never to give a child a book you would not read yourself.
