YOU SAID:
Be who you are and say what you feel, because those who mind don’t matter and those who matter don’t mind.
INTO JAPANESE
気にする人は関係なく、重要な人は気にしないので、あなたが誰であるか、あなたが感じることを言ってください。
BACK INTO ENGLISH
No matter who cares, the important person doesn't care, so say who you are and what you feel.
INTO JAPANESE
誰が気にしても、重要な人は気にしないので、あなたが誰であるか、あなたが何を感じるかを言ってください。
BACK INTO ENGLISH
No matter who cares, the important person doesn't care, so say who you are and what you feel.
That didn't even make that much sense in English.
