Help! !!!!!!
If I could change one thing about my personality, it would be to be more humble because it makes me more wiser.

I don't think "more wiser" is acceptable in English....... maybe "it makes me wiser". But then, that wasn't your question.
Si pudiera cambiar una cosa de mi personalidad, sería volverme más humilde, porque me me hace más sabio.
