人都是这山望着那山高，对自己的现状没有满意的时候。

[误] Almost all people think that the other mountain is higher than the one he's standing on. They never feel
saisfied with what they've already got.

[正] Almost all people think that the grass is greener on the other hill. They never feel saisfied with what
they've already got.

注：“这山望着那山高”是指人不满足于现状的心理，它在英语中已经有了现成的说法，即
the grass is greener on the other hill（他山的草更绿），因此我们借用即可，这样既方便又更有利于与西方人沟通。
