《颜氏家训·勉学篇》
他们之中有志向的，就能经受住磨炼，成就士族的事业；没有成就功业志向的，从此就懈怠懒惰，就成为平庸的人。
有志向者，遂能磨砺，以就素业；无履立者，自兹堕慢，便为凡人。
Those among them who have aspirations will be able to withstand hardships and achieve an illustrious career. Meanwhile, those who don’t have the will to achieve accomplishments will become lazy and mediocre.
