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.

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.

Good humor isn't a trait of character, it is an art which requires practice.
