The longer we dwell on our misfortunes, the greater is their power to harm us.

I know that I am intelligent, because I know that I know nothing.

I knew I belonged to the public and to the world, not because I was talented or even beautiful, but because I had never belonged to anything or anyone else.

As we look ahead into the next century, leaders will be those who empower others.

Man is the only creature that refuses to be what he is.
