YOU SAID:
I want to be the very best like none ever was
INTO JAPANESE
私は今までになかったように最高になりたいです
BACK INTO ENGLISH
i want to be the best i've ever been
INTO JAPANESE
今までで一番になりたい
BACK INTO ENGLISH
i want to be the best ever
INTO JAPANESE
私は史上最高になりたい
BACK INTO ENGLISH
i want to be the best ever
That didn't even make that much sense in English.
