53．聪明且勤奋

 聪明且勤奋。勤奋可加快实现你反复考虑过的计划。蠢人常因匆忙而失败，他们无法掌握要领，行事缺乏准备。而智者则不然，他们常因拖延而失败，他们深谋远虑，再三斟酌，这种耽搁往往让他们无法及时作出正确判断。但是，做事敏捷就是好运之母。讲求效率，事不隔夜，可成就良多。“忙里偷闲，缓中带急”，确是金玉良言。

53．Be diligent and intelligent 

Be diligent and intelligent. Diligence promptly executes what intelligence slowly excogitates. Hurry is the failing of fools: they know not the crucial point and set to work without preparation. On the other hand, the wise more often fail from procrastination: foresight begets deliberation, and delay often nullifies prompt judgment. Celerity is the mother of good fortune. He has done much who leaves nothing over till tomorrow. "Make haste slowly" is a royal motto.
