"...In war certain verities endure: threaten your enemy's line of supply. Get on his side, rear, or above him. Move fast and unpredictably according to a plan and when it's time, know it and fight. Communicate. Have heart. Show it. Triplecheck. Ruthlessly advance the best people. Don't quit. If you must, postpone and advance a different way. Waiting your chance is different from dallying. Admit error, if only to yourself. Learn hard from your mistakes. Adjust fast to change. And when you go, go..."
