idk, I think theres more like-minded people in public than there are in private and it wouldn't cost as much. Also, maybe going to public would help me learn to talk to people without coming off as stupid, take criticism properly, keep connections with other people and deal with assholes correctly.
It's funny you say that, because my experience is completely the opposite. It's not a matter of private or public, it's simply the environment you're in. I highly suggest you attend a school that is multicultural, because that's where you're going to meet a lot of different people with different outlooks; it will change you.
