翻译英文:不必太在乎

You do not need to care much.

(do 在这里有强调的意思）

don't worry too much
never mind
take it light

楼下的你太对了！我平时就喜欢说那句，但我不知道为什么刚才想不起来，哈哈

Don't care,这是最简单的说法。
还可以说， Don't worry too much of something.

do not be too care

take it easy
it is a piece of cake
don't worry

You do not have to take it too seriously.
Don't care too much.
Take it easy!
