The first duty of a man is to think for himself.
人的首要职责是为自己思考。
为儿童写作是一种责任——他们应该得到真相，即使真相很难。
"Memory is a strange thing. It doesn't work like I thought it did. We are so used to thinking of it as a camera or a tape recorder, but it's not like that at all. It's more like a painter. It creates a picture, but it's not always the same picture."
永远要黑白分明、百折不回。你的诚信必须要毋庸置疑。当一个人不需要付出代价或承担后果的时候，坚持做正确的事情并非难事。但当必须得放弃一些东西时，你就很难保持信用记录。要始终言而有信，不要为了自己的利益误导任何人。
人心充满私欲，所以危险；道心符合天理，所以精妙。
竞争是好事，它迫使你不断进步。
