To see a world in a grain of sand, and a heaven in a wild flower, hold infinity in the palm of your hand, and eternity in an hour.

Don't let yesterday take up too much of today.

To act agreeably to our nature is virtue.

The universe is not only stranger than we imagine, it is stranger than we can imagine.

你知道的越多，感觉到的越少。

I’m not afraid to fail. I’m not afraid to fall. That’s life. You fall, you get back up.

一本书是作者与读者之间跨越时空的对话。
