当人们知道目标是什么以及为什么时，他们的工作效果会更好。人们期待早晨去工作并享受工作是很重要的。

Nature is wont to hide itself.

Civilization is a stream with banks. The stream is sometimes filled with blood from people killing, stealing, shouting and doing the things historians usually record, while on the banks, unnoticed, people build homes, make love, raise children, sing songs, write poetry and even whittle statues. The story of civilization is the story of what happened on the banks.

风险不在于我们目标太高而失败，而在于我们目标太低而成功。
