The Art of War by
Sun Tzu, 600 BC.
[source]A skilled commander seeks victory from the situation and does not demand it of his subordinates.
The general who advances without coveting fame and retreats without fearing disgrace, whose only thought is to protect his country and do good service for his sovereign, is the jewel of the kingdom.
The general who wins the battle makes many calculations in his temple before the battle is fought. The general who loses makes but few calculations beforehand.
If words of command are not clear and distinct, if orders are not thoroughly understood, the general is to blame. But if his orders ARE clear, and the soldiers nevertheless disobey, then it is the fault of their officers.
Too frequent rewards indicate that the general is at the end of his resources; too frequent punishments that he is in acute distress.
