在事业的峰峦上，有汗水的溪流飞淌；在聪慧的珍珠里，有勤恳的心血闪光。

Sweat streams flow on the peaks of career; diligent blood shines in the pearls of wisdom.

40、才调是刀刃，艰苦是磨刀石，很尖锐的刀刃，若日久无庸磨，也会生锈，成为废料。

Talent is the blade, hard work is the grinding stone, very sharp blade, if not grinded for a long time, it will rust and become waste.

41、天行健，小人以自强不息。

As Heaven keeps vigor through movement, a gentleman should unremittingly practice self-improvement.
