一把旧钥匙上有一句意义深远的铭文——如果休息,我就会生锈。对那些因懒散而烦恼的人来说,这是至理名言。甚至最勤勉的人也可以以此为警示:一个人如果有才能而不用,就像废弃钥匙上的铁一样,会很快生锈,最终无法完成需要用到这些才能的工作。 There is a far-reaching inscription on an old key - if I rest, I rust. This is the wisdom of those who are troubled by laziness. Even the most diligent people can use this as a warning: If a person can not use talent, just as the iron on the abandoned key, it quickly rusts and eventually can not complete the work that requires them.
