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.

我不让意见定义我，我让它们磨砺我。

"Los silencios en una novela suelen gritar más fuerte que las palabras."

应对未来的唯一方法是在现在高效地运作。

“唯一永恒的是现在。”
