I haven't read the whole thread but the title got me to think. I'm going to comment on this in a general way, and the following might be, let's say not very popular, but here you go.
Something I keep on hearing and reading around me and in these sort of forums is the general sentiment of "Who cares what others think? Be happy in your own way!". I contend that while this view has some merit, it has a deep flaw: it antagonizes other people. Simply put, no, you're not going to be very happy if you take that as your mantra. The reason is simple: Deep down, we all have a wish of confirmation, affirmation -- that someone comes along and says, "I relate!". If not this, it is, at the very least, acknowledgment that we seek. I don't care if MBTI says that you're 120% introverted, to be honest, as MBTI, if you haven't noticed by now, serves to feed you this same thing on a platter.
Now this has nothing to do with the affirmation along the lines of "aww *hug* I feel for you!", or "I'm sorry for your loss.". Let's say you have a streak of misanthropy, you dislike other people. Let's say you have a blog where you air your (coherent, intelligent; not blind hate) views. Is this an uncommon scenario? Probably not. If I were to ask you why you blogged, you'd probably answer with something around the "To explore my mind's depths; to voice my thoughts in a purified medium" area. But no, my friends, it's more than that; you blog because you want *someone* to just happen his/her way into the blog, read the tendrils of your mind, and (vocally) agree with you. And even if that someone (vocally) disagrees with you, if you made them think, to consider your idea, then you're successful, you've been acknowledged. You could say that we're all posting here for the same reasons. I know I'll be the first one to admit it.
And this is why the "Don't you mind other people!" advice falls flat. Chances are, no, you can't do that. What you can do is to first try to act genuinely, at least in your understanding of "genuine", and then gauge the reactions, instead of trying it the other way. Trust me, it becomes a whole lot easier if you just act, (I don't mean this as in "improvise the hell out!", as that's a seperate talent, I mean this as in "do not moderate your thoughts preemptively"). Some people will always think you're a fuckwit, but there's a good chance that if you're genuine, someone will eventually pick that up and reward you with the attention and the affirmation you, and all of us with you, crave deep down. And the ultimate reward will be remembrance.
