——韩愈《进学解》

格言大意：学业由于勤奋而精进，由于嬉戏而荒废。

Main Idea: One will study well and make progress if one works hard. One would neglect one’s studies if one plays all day.

李密专心读书（Li Mi putting his whole heart in reading）

  隋朝时的李密专心学习，不愿意浪费一点儿时间。小时候他出门，把要阅读的书挂在牛角上，一边骑牛一边读书。长大后，有一次他从一个有名的大臣身边经过，都没有察觉到。那个大臣很敬佩李密学习的专心和勤奋。
