"The only real progress lies in learning to be wrong all alone."

"Leadership is not about titles, positions, or flowcharts. It is about one life influencing another."

It is no good to try to stop knowledge from going forward. Ignorance is never better than knowledge.

想想看，人类愚蠢到会去小心地避免那些可能使他们造成伤害的臭鼬或是狐狸，却不担心狮子对他们安全造成的威胁。
