诗人必须成为先知，使自己成为先知。
The poet must be a seer, make himself a seer.
我收到的最好的建议是忠于自己，永远不要妥协我的正直。
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.
成功的关键是不断尝试，即使第一次没有成功。
