English Translation
What is good for you is good for me.
“ti” is spelled wrong in that Spanish phrase. The correct spelling should be “tí” with an accent mark: “Lo que es bueno para tí es bueno para mí”
The word “tí” is a prepositional pronoun in Spanish and requires an accent mark to distinguish it from “ti” (which can be a musical note). Both “tí” and “mí” in this phrase should have accent marks to follow Spanish orthographic rules.
So the correct phrase is:
“Lo que es bueno para tí es bueno para mí”
(What is good for you is good for me)
