Treat every problem with reason.

You have to keep thinking about what you can do to make the world a better place.

You see things; and you say, 'Why?' But I dream things that never were; and I say, 'Why not?'

最高尚的快樂是理解的喜悅。

釋義：能夠清楚自己所要達到的目標并最終實現了自己的目的，這樣的人是可以和他們研討細微事物的，他們知道在該終止的時候就及時地終止，這樣的人是可以同他們一起共同保存道義的。
