Miur, I cannot help but read a little sceptism about if even I are an INFJ in what you wright. If so, I don't blame you, and I will not hide that even the slightest of critic will make me start my own "inner scan" of what's true or not. "Am I REALLY an INFJ?!" As you mentioned, being an INFJ are obvious, since you've always felt like your different to everybody else. I cannot say that this has been the case for me... but then again, that depends on what you mean about it. I have always, ALWAYS been different to every "normal" man or women, and that difference is due to my deep searching for truth, for understanding, and so forth - the big introspectiv intuition, as I've learned to call it 6 months ago. Then theres this great hearth for others... I cannot say that even this has been that obvious for myselt, as I've always identified myself as an thinker. So my first thought before taking the test long ago was that "i ought to be a thinker", but then tests showed that I'm in fact a feeler. What does this mean? Well, what I've thought was "thinking", has always been my intuition (of course it's just a choice of words, but lets stick to the MBTI's way of conceptualization). So why "feeling"? That's because I've always first ask what others want, what others might benefit from my choices, and every decision I've made in life has always had that part of going trough the possibilities of "what would happen if this person moved there, or if I stayed and merried that girl" and so on. Never has it been the logical choice at first glance. There HAVE been a logical questioning of my feelings and choices though, going trough my intentions and others will, trying to put every other aspects away and see it from "the right angle", but this tends to bring me to an unhealthy state of mind. I get to cought up in details, in "the one choice" and loose my sight of life: being it living in harmonie with myself and everyone else.
And so last the sensing... I cannot doubt that I'm bad at taking in the invironment with my senses due to my ability to use my intuition, it's something that goes "hand in hand".
So am I an INFJ after all? Well, I cannot say that it has been so obvious to me, but when I started thinking about it I cannot see any other possibility. Does the fact that I used logic to figure out the "only possibility" make it less true that i should be an INFJ? I cannot tell. That would probably make me an INTJ, perhaps, but that I doubt even more then being an INFJ, since I have a lot of INFJ friends, and they are quite different to me in interaction with the world outside of their heads.
Oh, I nearly forgot I and J. Never in my mind that I would be extroverted, nope (my world of intuition is in my head, my own little private world), and J is a product of the fact that when given a new task I cannot find rest untill it's finished... and then I "go back" to my normal state of mind, in peace and quite, unstressful life (wich really rather is a P, but that's exactly what an INFJ is deep down: introverted percieving, extroverted judging.
So, this could be considered as my "defence" against any doubt that I would be an INFJ - others or my own - but still there is always a little doubt in my heart, as always, as it probably should be, I guess. But it isn't obvious... unfortunately.
I'm not giving this long speach to make anyone feel bad, so if that's the case, I apologise. Not that I now can see how anyone could take it as offensive, but my experience tells me that you can never forsee how others interpreters comments on the internet. My heart is kind, and my intention is to make it clear that i do believe that I'm truely an INFJ, but also that I'm still questioning that statement. That's just part of being me... INFJ or not.
