I divide my officers into four groups. There are clever, diligent,  stupid, and lazy officers. Usually two characteristics are combined.  Some are clever and diligent -- their place is the General Staff. The  next lot are stupid and lazy -- they make up 90 percent of every army  and are suited to routine duties. Anyone who is both clever and lazy is  qualified for the highest leadership duties, because he possesses the  intellectual clarity and the composure necessary for difficult  decisions. One must beware of anyone who is stupid and diligent -- he  must not be entrusted with any responsibility because he will always  cause only mischief.
