出自包天笑翻译的日本小说《不如归》中引用的古诗。

The chief beauty about time is that you cannot waste it in advance. The next year, the next day, the next hour are lying ready for you, as perfect, as unspoiled, as if you had never wasted or misapplied a single moment in all your life.

懦夫从不启程，弱者死于途中，只剩我们前行。

数学的语言是普遍的，超越了文化和语言的障碍。

尽一切职责，而不希望得到任何回报。
