The people who talk about themselves a lot should blend some more creativity into it so they don't end up being called out on it then acting sullen. It would show that they have plenty of talent if they did. The kind of talent that can't be faked or stolen, lending people to be more interested in them. It could be a bit of a challenge but it's better than being silent about their excellent self, if they all took the time then it would be equivalently interesting as anything else, amirite?
