I know this wouldn't make a moving feel-good movie, but . . .
there's "being yourself" and there's being yourself. One involves keeping your own style but generally finding socially acceptable ways to display it; the other is aggressively saying "If you don't like me exactly as I want to be, F you." The former will (eventually) help you find friends; the latter not so much. Examine what it is that makes you unpopular and try to make an unbiased judgement about how important that element is to you - is your right to insert broadway show tunes into conversation whenever possible a part of "who you are" you need to cherish, or is it a habit you could tone down if it's keeping you from making friends?
I think this is really good advice. It kind of goes along with what I said earlier, in that it can be said/interpreted in a bad way or a useful way. In my post the advice was about asking yourself why you want to be friends with certain people who are in very different circles, and if you really have a solid basis for a friendship with them or if you just like them because they're popular--which can also be phrased as, "Keep your head down and don't try to reach out beyond your circle."
One of my co-workers for five long years was a guy, Mike, who wasn't inherently bad, but he'd been a social outcast since elementary school and even now reeked of desperation and insecurity, which he tried to camouflage by being an obnoxious know-it-all who couldn't handle the slightest bit of constructive criticism or advice. That meant people were trying to "CHANGE HIM" and he just wouldn't put up with it! Never mind the fact that healthy people grow, mature, evolve, adapt to changing circumstances, try new strategies if their current ones aren't working for them, and realize that friendship is a two-way street involving the occasional compromise.
Unlike a lot of these stories, I'm please to report that Mike did actually have a couple of friends here (though he wanted more, and a girlfriend); and that at the next place he worked, he met his current wife.
But I think his adult life (not to mention my office life) would have been a lot less stressful if he'd been more self-aware and open to change--secure enough in himself to admit that he might need
to change in small ways now and then.
