「必要なのは、共に働く人々が互いに親切であることだけではない。必要なのは規律だ。規律は難しい。私たちは生まれつき欠点だらけで移り気で、細部への注意ではなく新しさと興奮のためにできている。規律とは、努力して身につけるものなのだ。」
"What is needed, however, isn't just that people working together be nice to each other. It is discipline. Discipline is hard--harder than trustworthiness and skill and perhaps even than selflessness. We are by nature flawed and inconstant creatures. We are not built for discipline. We are built for novelty and excitement, not for careful attention to detail. Discipline is something we have to work at."
