A wise man said: before you speak， let your words pass through three gates. At the first gate， ask yourself， "Is it true？" At the second gate， ask "Is it necessary？" At the third gate， ask， "Is it kind？"

选择理论忽略了我们所知道的关于人类的大部分知识。

【译文】 孔子说：“老好人是败坏道德的人。”

我不逃避挑战，我奔向挑战。

The secret of change is to focus all of your energy not on fighting the old, but on building the new.
