有时候，最深的痛苦来自于我们无法表达的情感。

Our heroes are human heroes. That's a very new situation. Most other societies have had, right at their center, the worship of something transcendent: a god, a spirit, a natural force, the universe, whatever it is -- something else that is being worshiped. We've slightly lost the habit of doing that, which is, I think, why we're particularly drawn to nature.

我喜欢创作既易于理解又有深度的作品。
