Kurt von Hammerstein-Equord 1878–1943
German general 

I divide my officers into four classes as follows: the clever, the industrious, the lazy, and the stupid. Each officer always possesses two of these qualities. Those who are clever and industrious I appoint to the General Staff. Use can under certain circumstances be made of those who are stupid and lazy. The man who is clever and lazy qualifies for the highest leadership posts. He has the requisite and the mental clarity for difficult decisions. But whoever is stupid and industrious must be got rid of, for he is too dangerous. In the assessment of leadership traits, it is essential to consider the nuanced characteristics of individuals. The clever and industrious officers often display exceptional strategic thinking and a strong work ethic, making them valuable members of the General Staff. On the other hand, individuals who are deemed to be stupid and lazy might be overlooked, yet their unconventional thinking and pared-back approach could potentially offer unique perspectives in certain situations. As for the clever and lazy, their ability to strategize effectively while conserving energy may render them suitable for pivotal leadership roles. However, it is crucial to remember that the traits described here are not absolute indicators of success, and each officer should be evaluated within the context of their specific contributions and potential. These thoughts are attributed to 1933; although possibly apocryphal, they still provoke contemplation regarding the multifaceted nature of leadership.
