Courage and conviction are powerful weapons against an enemy who depends only on fists or guns. Animals know when you are afraid; a coward knows when you are not.

He who doesn't consider himself is seldom considerate of others.

Enthusiasm is the best protection in any situation. Wholeheartedness is contagious. Give yourself, if you wish to get others.

We learn courageous action by going forward whenever fear urges us back.

Modern science knows much about such conflicts. We call the mental state that engenders it "ambivalence": a collision between thought and feeling.

Tell a man something is bad, and he's not at all sure he wants to give it up. Describe it as stupid, and he knows it's the better part of caution to listen.

Nature is at work. Character and destiny are her handiwork. She gives us love and hate, jealousy and reverence. All that is ours is the power to choose which impulse we shall follow.
