The fountain of content must spring up in the mind, and they who have so little knowledge of human nature as to seek happiness by changing anything but their own dispositions will waste their lives in fruitless efforts.

Success is about consistency and dedication.

如果你想成功，你必须对你生活中经历的一切承担100%的责任。

1985年2月的一次演讲时所说

记忆不是忠实的记录；它是对过去的主动重建。
