I've known I was an INTJ for a long time. When I worked in the Info-tech industry I just blended in really nicely. XNTXes abounded there. Lots of my collegues were male INTJs or male/female ENTJs and a few Ps and the sales folks tended to be ENFX. Now I work / study in a much more touchy feely domain - I feel like an alien. They all tend to be xSFx.
So in looking for ways to deal with the change constructively I find myself joining here.
My closest friends (few that there are) are INTJ men . My significant others have tended to be ENTJs - high energy relationships to say the least.
So here I am doing a real INTX thing. Joining an online community.
