可持續性不是一種選擇；它是我們對后代的責任。

The most exciting phrase to hear in science, the one that heralds new discoveries, is not 'Eureka!' but 'That's funny...'

生活中最好的老師是經驗。

記憶對于不重復過去的錯誤至關重要。

Sir, where are you running? Are you doing this for world peace? Are you doing this for the homeless? Are you running for women's rights? The environment? They just couldn't believe that somebody would do all that running for no particular reason. Why are you doing this? I just felt like running. I just felt like running.

Eliminating clutter makes room for your true treasures.

我不完美，但我一直在努力改進。

這是最好的時代，也是最壞的時代；這是智慧的時代，也是愚蠢的時代；這是信仰的時代，也是懷疑的時代；這是光明的季節，也是黑暗的季節；這是希望的春天，也是絕望的冬天；我們什么都有，也什么都沒有；我們正走向天堂之路，也正走向地獄之門。

一定要成功﹗我只以成敗論英雄。
