No man really knows about other human beings. The best he can do is to suppose that they are like himself.

Sustainability isn't an option; it's a responsibility we owe to future generations.

The person who tries to live alone will not succeed as a human being. His heart withers if it does not answer another heart. His mind shrinks away if he hears only the echoes of his own thoughts and finds no other inspiration.

I don't believe in luck. I believe in preparation meeting opportunity.
