Judge people by their actions. The brilliance of warfare is that no amount of eloquence or talk can explain away a failure on the battlefield. A general has led his troops to defeat, lives have been wasted, and that is how history will judge him. You must strive to apply this ruthless standard in your daily life, judging people by the results of their actions, the deeds that can be seen and measured, the maneuvers they have used to gain power.
