"The world is a book, and those who do not travel read only one page."

The end of history will be a very sad time. The struggle for recognition, the willingness to risk one's life for a purely abstract goal, the worldwide ideological struggle that called forth daring, courage, imagination, and idealism, will be replaced by economic calculation, the endless solving of technical problems, environmental concerns, and the satisfaction of sophisticated consumer demands.

韧性不是避免失败；而是从中学习和成长。

水从山上流到滩头不是有意的，白云从洞中穿过也是无心的。

释义：追求的过程本身比结果更能定义幸福。
