Success comes from persistence and the willingness to learn from failures.

创新不仅仅是创造新事物，而是让现有的事物变得更好。

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.

不是要成为最好的，而是要变得比昨天更好。
