All very successful commanders are prima donnas and must be so treated.
Discipline must be a habit so ingrained that it is stronger than the excitement of battle.
Do your duty as you see it, and damn the consequences.
To conquer, we must destroy our enemies. We must not only die gallantly; we must kill devastatingly. The faster and more effectively you kill, the longer you will live to enjoy the priceless fame of conquerors.
Keep going, someone must be on top, why not you?
If we take the generally accepted definition of bravery as a quality which knows no fear, I have never seen a brave man. All men are frightened. The more intelligent they are, the more they are frightened.
