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.

True leadership is about empowering others to achieve their full potential.

科学的美在于它让我们看到的不是世界的现状，而是它可能的样子。
