图书馆里栖息着夜晚从书页中走出的幽灵。
"The library is inhabited by spirits that come out of the pages at night."
The more you know, the more you realize you don't know.
Introspection is the only method by which the mind can be directly observed.
你脑袋里有大脑，鞋子里有双脚，你可以选择任何方向前进。
——致书蒋介石，1920年10月29日
如果两分钟后觉得无聊，就试四分钟。如果仍然无聊，就八分钟。然后十六分钟。然后三十二分钟。最终你会发现它一点也不无聊。
