时至今日，我从未在任何地方选修过化学、经济学、心理学或商业课程。
To this day, I have never taken a course anywhere, in chemistry, economics, psychology, or business.
We don't ever let go of anything, we just go on to the next thing.
I had ambition not only to go farther than any man had been before, but as far as it was possible for a man to go.
可能性的极限只能通过超越它们进入不可能来定义。
天地没有偏爱，对待万物像对待草扎的狗一样，任其自生自灭。
现实主义不是复制自然，而是理解其本质。
不要试图去做一个成功的人，要努力成为一个有价值的人。
无限的努力是打开潜能的关键---而不是实力与头脑。
未来属于那些能够跨越界限合作的人。
