語出（南宋）崔敦禮《芻言》。自以為聰明的人，其實并不聰明；自以為能干的人，其實并不能干。

一本書就是你手中握著的夢想。

Mathematics is the poetry of logical ideas.

The only way to deal with an unfree world is to become so absolutely free that your very existence is an act of rebellion.

Challenges are opportunities in disguise—if you're willing to look closely.

Start where you are, with what you have. Make something of it and never be satisfied.

"Never confuse movement with action."

The novel is an artifact that, like a bomb, can explode in the reader's consciousness.
