Be an example to your men

"Be an example to your men, in your duty and in private life. Never spare yourself, and let the troops see that you don't in your endurance of fatigue and privation. always be tactful and well-mannered and teach your subordinates to do the same. Avoid excessive sharpness or harshness of voice, which usually indicates the man who has shortcomings of his own to hide."
- Field Marshall Erwin Rommel
