The true historian is a soldier of truth.

真相是，过去是我们所拥有的一切。我们无法改变它，但我们可以从中学习。

The choices we make each day—what we buy, what we eat, how we live—all have an impact.

写作就像做爱。不要担心高潮，专注于过程就好。

Have the courage to follow your heart and intuition. They somehow already know what you truly want to become.

创新的关键不仅在于找到答案，还在于提出正确的问题。

可持续采石不是选择，而是我们对后代的责任。
