There is no perfect person in the world. Although you say that someone is so perfect, she/he has a weakness. So, we have our strength and our weakness and it's different for every person.
Like me. Even some people say that I'm perfect or great, but I'm far from that. I have many kind if weakness too. If there is a people say that my music is great, it's not 100% true. My music is not perfect.
So, there is no 100% perfect people in the world.
