——贈宋慶齡題詞，1922年

可持續性已不再是一種選擇，而是我們對后代的責任。

The best leaders are those who listen more than they speak.

Communicate everything you possibly can to your partners. The more they know, the more they'll understand. The more they understand, the more they'll care. Once they care, there's no stopping them.

The most effective way to destroy people is to deny and obliterate their own understanding of their history.
