工程师是创造未来的人。他们是改变世界的人。

I have a dream, and that dream is worth every sacrifice I make.

The idea is not to live forever, it is to create something that will.

A journey is a person in itself; no two are alike. And all plans, safeguards, policing, and coercion are fruitless. We find after years of struggle that we do not take a trip; a trip takes us.

我不是表演，我是奇观。
