So I usually don't put too much stock in these things, except when I do, and
http://www.geocities.com/lifexplore/intj.htm does seem to kind of describe me to a T. Oh yes.
Like:
By nature, INTJs are independent individualists. They see their visions so clearly that they are often surprised when others do not see things the same way. INTJs are strong at critiquing and as a result tend to notice the negatives. To them, a job well done should be reward enough in itself. They may neglect to comment favorably on others' contributions. Yes.
They prefer to work in a place in which the future can be planned and where they can work for change in an organized manner. Yes yes.
They tend to withhold their deep feelings and affections from the public and sometimes even from the object of their affections. They can be intensely loyal and caring, even though this is not always expressed in words. Yes yes yes.
If an idea or position makes sense to an INTJ, it will be adopted, if it doesn't, it won't, regardless of who took the position or generated the idea. As with the INTP, authority per se does not impress the INTJ. Nope. Never has.
INTJs manipulate the world of theory as if on a gigantic chess board, always seeking strategies and tactics that have high payoff. Yes, except real people and situations just don't make sense a lot of the time, so it's necessary to construct grandiose alternate realities where there are characters that feel every bit as real as "real" people and things. That's like a gigantic chess board, but you actually get to deal yourself a hand big enough to move the pieces (or hell, the whole board) if desired, instead of just waiting around hoping that eventually, the "long-term" mindset will pay off and someone will finally let you get to that extra pawn.
Consequently, there's nothing that compares to these alternate realities, nothing. But being part of the chess board itself can have its own rewards. Makes life interesting. Always something new to learn - and I don't mean that in an opportunistic way. Etc.
This tendency of people to feel transparent in the presence of the INTJ often result in relationships which have psychological distance. Unfortunately...
The emotions of an INTJ are hard to read, and neither male nor female INTJ is apt to express emotional reactions. Except, of course, when it all comes out at once - which comes from: At times, both [male and female, cause it's a teeny bit sexist] will seem cold, reserved, and unresponsive, while in fact INTJs are almost hypersensitive to signals of rejection from those for whom they care. Yeah. That. (Which leads to the all-at-once-ness.)
INTJs are vulnerable in the emotional area and may make serious mistakes here. But we can learn, we can, we can. (And have.)
The end.
