Many people consider MC as a scary thing, but for professionals, when they have a strong mentality and are psychologically stable, they consider MC as an experience to change because with MC, yes, we can know what we did wrong with MC, we can know what what we can change from our own system because when we don't know what we did wrong, we won't be able to fix it. It's called fixing it. You have to know the mistake first so that we don't repeat the same thing.
