The first step in liquidating a people is to erase its memory. Destroy its books, its culture, its history. Then have somebody write new books, manufacture a new culture, invent a new history. Before long the nation will begin to forget what it is and what it was. The world around it will forget even faster.

The most dangerous phrase in the language is, 'We've always done it this way.'

The world is beautiful, but it has a disease called man.

你不尝试就100%不会成功。

A school should not just be a place to learn, but a place that inspires learning.

"Maybe you can afford to wait. Maybe for you there’s a tomorrow. Maybe for you there’s one thousand tomorrows, or three thousand, or ten, so much time you can bathe in it, roll around it, let it slide like coins through your fingers. So much time you can waste it. But for some of us there’s only today. And the truth is, you never really know."

译文：经常想到这个世上还有人的处境不如我，还有人的命运不如我，就该知足感恩了；经常想到有人的德行操守超过我，有人的学问超过我，就该感到惭愧而发愤努力了。赏析：人的欲望是无穷的，也是难以满足的。很少有人做到知足常乐。人总是喜欢和其他人对比物质方面的东西，别人有的，也希望自己有。而学问，德行，却很少有人去反躬自省。
