一个良好的世界需要知识、善良和勇气；它不需要对过去的后悔，也不需要被无知之人长时间前说过的话所束缚的自由智慧。
A good world needs knowledge， kindliness， and courage； it does not need a regretful hankering after the past or a fettering of the free intelligence by the words uttered long ago by ignorant men.
The best mining projects are those where local communities become true partners, not just stakeholders.
统计学是科学的语法。
一切人类知识都源于经验。
Every blank space is an opportunity to disrupt expectations.
Don't search for defining moments because they will never come. The moment that define you have already happened, and they will already happen again.
Hustle hard, hustle smart, but most importantly, hustle together.
——致书蒋介石，1920年10月29日
每一部伟大的作品都是作者与读者之间的一种无声对话。
还有什么智慧比善良更伟大？
