Defeat is Not Due to Losses but to the Destruction of the Soul [quote]
I am sure that if every leader who goes into battle will promise himself that he will come out either a conqueror or a corpse he is sure to win. There is no doubt of that. Defeat is not due to losses but to the destruction of the soul of the leaders.
The most vital quality a soldier can possess is SELF CONFIDENCE–utter, complete and bumptious. You can have doubts about your good looks, about your intelligence, about your self control but to win in war you must have NO doubts about your ability as a soldier.
– General George S. Patton (in a letter to his son)
