地道表达：
live by one’s wits
解词释义：
wit的本义是“智力，智慧”，by在这里表示方式，意思是“通过，靠，借助”。该短语的字面意思就是“靠智慧生活”，但是它是贬义词，所以live by one’s wits就是指“靠耍小聪明而不踏踏实实过日子”，即我们说的“混日子”。
支持范例：
Eg. Perhaps you may live by your wits but I don't hope so.
也许你可以靠小聪明混日子，但我不希望你这样。
Eg. He couldn't get a permanent job so I had to live by my wits for a couple of years.
他没能找到长久的工作，因此这两年来我只能靠骗人吃饭。
