“Intellectually, Ridcully maintained his position for two reasons. One was that he never, ever, changed his mind about anything. The other was that it took him several minutes to understand any new idea put to him, and this is a very valuable trait in a leader, because anything anyone is still trying to explain to you after two minutes is probably important and anything they give up after a mere minute or so is almost certainly something they shouldn’t have been bothering you with in the first place.”
