Learn to distinguish between tasks that deserve to be done excellently and tasks that just need to be done.

学会区分值得出色完成的任务和只需要完成的任务。

Never remain in company with those who have lost their reputation, even though they may not have deserved to do so; for society holds us responsible for our friendships as well as for our enmities.

切勿与名誉扫地的人为伍，即使他们不值得这样做；因为社会要求我们对我们的友谊和我们的敌意负责。
