I myself have ceased to adhere strongly to these "types", I know several INTJs (oddly enough none of them are mentally stable, 2 are psychopaths and one is a schizophrenic), but calling myself an INFJ just seems to be self-glorification.
If I am an INFJ, then I am, if that is what I strive to be, then I am not, if I call myself an INFJ, I think it leads to my own self-fulfilling prophecy.
It is a label I would apply to myself, and constrain myself to, I am me, you are you, and we don't need a bracket to fit into other than for our own comfort.
Saying all that, INFJs in general are cool people, but INTJs are (in my experience) a more interesting bunch.
Both of my INTJ psychopath friends find it "impossibly difficult" to see inside my head, whereas I can make semi-accurate estimations on their motives and the reasoning behind them. It may be because I may be an F and they are a T, but I think it goes deeper than that because I am both F and T in many cases.
I believe myself fundamentally differing to virtually every other human I meet (and I have met several INFJs), because I think in a detailed big picture where humanity is both near the bottom of the priorities, but the most essential factor in my plans, the forefront of my mind is dedicated to several things:
• The fate of the environment we destroy
• The fate of the animals who lived in that environment
• What I can do to keep humanity from destroying environments
• How can I keep the Internet a place of freedom and peace, not corporate interests
Those are my main concerns, and they are all rather large ones which I work towards.
I know I have little chance of making a difference, but by setting an example of myself, perhaps others will follow.
If this is INFJ behaviour, then I guess I may be an INFJ, but I am not an expert on cognitive functions or behaviours.
Apply to yourself at your discretion, and take it with a pinch of salt.
