“Whoever tries to place a man or staff an organization to avoid weakness will end up at best with mediocrity. The idea that there are ‘well-rounded’ people, people who have only strengths and no weaknesses (whether the term used is the ‘whole man,’ the ‘mature personality,’ the ‘well-adjusted personality,’ or the ‘generalist’) is a prescription for mediocrity if not for incompetence.”
