Hayley教口語(yǔ)，“不在行”用英語(yǔ)怎么說？

that’s an expression which means someone’s not very good at doing something and isn’t likely ever to be successful at doing it

這是個(gè)短語(yǔ)表達(dá)的意思是某人并不擅長(zhǎng)做事情，并且不會(huì)在這方面取得成功。

A: Hey. What do you think of my acting? I'm gonna be a famous actor.

嘿，你覺得我演技咋樣?我會(huì)成為一個(gè)明星!

B: Well, don't give up the day job!

額，別浪費(fèi)時(shí)間了。
