Worry about yourself?

Why is everyone so worried about being 'cool' or accepted by the masses? Who really gives a crap? In the end, it's just you. You've got to wake up everyday, regardless if you wake up with anyone else, there's no one else there in your head. Well, unless you happen to be one of the few with a couple of extras up there between your ears. I guess what I'm really getting at is, why's it so important to each of us to be loved and accepted by either those we know or those we don't know? When it's really only us that we should really be worrying about. It's just you that can stomach you every day, so take care of yourselves and look out for each of you out there.
