《资治通鉴·晋纪·晋纪十五》
他常常对人说： 大禹这样的圣人，尚且珍惜每寸光阴，至于一般人，应当珍惜每分光阴。怎能只求逸游沉醉，活着对时世毫无贡献，死后默默无闻，这是自暴自弃！ 
常语人曰： 大禹圣人，乃惜寸阴；至于众人，当惜分阴，岂可但逸游荒醉！生无益于时，死无闻于后，是自弃也！ 
He often said to people: "A saint like Dayu still cherishes every inch of time, and as for ordinary people, they should cherish every minute of time. How can they only seek to escape and become intoxicated, live without contributing to the times, and die in obscurity? This is self-abandonment!"
