To feed the world, we must first learn to respect the limits of our planet.

In the end, we will remember not the words of our enemies, but the silence of our friends.

To write is to give oneself over to the world, to let the world in, and to let it change you.

我不是白天，我是黑夜。

译文：天地永恒无穷尽，生命短暂很有限，过一天就少一天。荣华富贵自古以来就有定数，但学问则无定数，只要花费一份力，就会收获一分知识。赏析：这句话告诉我们，生命和青春有限，要懂得珍惜生命和时间，不要挥霍无度。我们要在有限的生命里，多读书学习，那么就会有收获。
