"If an undertaking was easy, someone else already would have done it. - If you follow in another's footsteps, you miss the problems really worth solving. - Excellence is born of preparation, dedication, focus, and tenacity; compromise on any of these and you become average. - Every so often, life presents a great moment of decision, an intersection at which a man must decide to stop or go; a person lives with these decisions forever. - Examine everything; not all is as it seems or as people tell you. - It is easiest to live with a decision if it is based on an earnest sense of right and wrong. - The guy who gets killed is often the guy who got nervous. The guy who doesn't care anymore, who has said, "I'm already dead--the fact that I live or die is irrelevant and the only thing that matters is the accounting I give of myself," is the most formidable force in the world. - The worst possible decision is to give up."
