As a proverbe the sentence "Je suis ce que je suis" means "I am that I am"/"I am what I am"/"I am as I am".
But in other contexts, it can be any of these combinations: I am what I am I am what I follow I follow what I am I follow what I follow.
Actually "Je suis" meaning "I follow" and "Je suis" meaning "I am" are both written and pronounced the same.
