"The most important thing in a book is the story. The illustrations are there to support and enhance the story, not to overshadow it."

The only way to learn mathematics is to do mathematics.

譯文：能夠結交正直的朋友，這樣的人一定會有好名聲；愿意親近德高望重的長者，這樣的人一定會有好事發生。賞析：什么樣的朋友可以交，什么樣的朋友不可交，我們應該懂得篩選。益友會給我們帶來好的改變，損友只會讓我們越來越壞。蓬生麻中，不扶而直。我們應該與品德高尚，心術端正的人交往。

A story is never finished; it only stops.

Museums are the cemeteries of art.
