I'm as proud of many of the things we haven't done as the things we have done.Innovation is saying no to a thousand things.

True progress is measured not just in profits, but in the positive impact we have on society.

The true discovery of America is before us. The true fulfillment of our spirit, of our people, of our mighty and immortal land, is yet to come.

普遍来说，一个人的力量是他目前的手段，用来获得某些未来的明显好处。

我不知道我想要什么。我反复无常、不坚定、被动；我喜欢不确定、无边界，以及持续的不确定性。
