I don't like to lose, and that isn't so much because it is just a football game, but because defeat means the failure to reach your objective. I don't want a football player who doesn't take defeat to heart, who laughs it off with the thought, "Oh, well, there's another Saturday." The trouble in American life today, in business as well as in sports, is that too many people are afraid of competition. The result is that in some circles people have come to sneer at success if it costs hard work and training and sacrifice.
