“I divide my officers into four groups: smart, diligent, stupid, and lazy. Usually two characteristics are combined. Some are smart and diligent—their place is the General Staff. Some are stupid and lazy—they make up 90 percent of every army and are suited to routine duties. Some are both smart and lazy; they are qualified for the highest leadership duties, because they possess the intellectual clarity and the composure necessary for difficult decisions. Beware of those who are stupid and diligent—they must not be entrusted with any responsibility because they always cause mischief.”
