The world is indeed full of peril, and in it there are many dark places; but still there is much that is fair, and though in all lands love is now mingled with grief, it grows perhaps the greater.

I think it's important to take risks in life. If you don't take risks, you'll never grow.

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.

我将继续努力推进这项研究，我相信这不仅是一种推测，而且具有足够的重要性，能激发它成为对人类有实质性益处的美好希望。
