可持续性已不再是一种选择，而是我们对后代的责任。

I don’t write for an audience. I write for myself.

写作是一种思考方式，而不仅仅是思想的记录。

I believe in the power of storytelling to change people's lives.

Every person must have a thought that changes them, or a book, or a word, or a moment; and if they don't, their life is wasted.

和平是最高的善，因为它是心灵与其本性最完全一致的状态。
