思想需要书来磨砺，正如宝剑需要磨刀石。

艺术家必须是无限的孩子。

翻译：善行不积累不足以成就美名，恶行不积累不足以灭亡自身。

I've been waiting more than 30 years to say this: "Dad, I always told you I'd come back and get my degree." I want to thank Harvard for this timely honor. I'll be changing my job next year…and it will be nice to finally have a college degree on my resume.

Oh,to struggle against great odds,to meet enemies undaunted.

The only way to do great work is to love what you do.
