Seek always to do some good, somewhere. Every man has to seek in his own way to realize his true worth. You must give some time to your fellow man. For remember, you don't live in a world all your own. Your brothers are here too.

Reverence for Life affords me my fundamental principle of morality, namely, that good consists in maintaining, assisting, and enhancing life and that to destroy, harm, or to hinder life is evil.
