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.

"History is not the past. It is the method we have evolved of organizing our ignorance of the past."

Every artist dips his brush in his own soul, and paints his own nature into his pictures.

我生来就会犯错，而不是假装完美。
