我们都在阴沟里，但仍有人仰望星空。

We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too.

表演不是要成为不同的人。它是在明显不同的事物中找到相似之处，然后在那里找到自己。

The meaning of life lies in how we give it meaning.

成功不是终点，失败也不是末日。
