The only limit to our realization of tomorrow will be our doubts of today.

Now, I am not going to stand here and tell you that failure is fun. That period of my life was a dark one, and I had no idea that there was going to be what the press has since represented as a kind of fairy tale resolution. I had no idea then how far the tunnel extended, and for a long time, any light at the end of it was a hope rather than a reality.

最好的水果来自最好的实践；绝不能在标准上妥协。

I don't need a reason to be unstoppable.

最伟大的真理是最简单的，最伟大的人也是如此。

And never would they make a mistake in the order of their entry upon the stage. It would be magnificent.
