"There are two occasions when the sacred beauty of Creation becomes dazzlingly apparent, and they occur together. One is when we feel our mortal insufficiency to the world, and the other is when we feel the world's mortal insufficiency to us."

一八一四年，俄、奥、普联军兵临巴黎城下，理工学校学生要求参战。面临灭顶之灾的拿破仑却说：“我不愿为取金蛋杀掉我的老母鸡！”后来，这句名言被刻在巴黎理工学校梯型大教室的天花板正中心，一直激励着该校师生奋发好学。

The creative adult is the child who survived.

Leadership is about making others better as a result of your presence and making sure that impact lasts in your absence.

我们必须保持警惕，坚决与一切内外敌人作斗争。
