I've been best friends with an ENTJ for years. He's a very charismatic, bright, motivated guy. He has a huge social network, and people generally like him when he's in his charming mood. However, I'm one of the few people that is very close to him, mostly because people can't handle large doses of his obnoxiousness. Granted, he had a rough childhood, so he may not be a very "developed" ENTJ. This rarely got to me, however, because well... ISTPs are pretty indifferent to a lot of things. But when ENTJs are in an unhealthy, self-destructive state (which hopefully doesn't happen all that often, if ever), that's when I draw the line. This has been the case for my friend for the past year, and it was a violent, downward cycle. First, the obnoxiousness and his ego increased 10 fold. Next, the way I lived my life and the people in my life was heavily critiqued. Somewhere in there I tried confronting him about his destructive behavior (Something I really don't like to do), and he listened, but did nothing. My patience wore with him and he did one last thing that compromised our friendship. I'm sure we will make amends sometime in the future, but it's nearly impossible right now when everytime I try to explain to him why he upset me somehow it's not his fault but as a result of my own actions. Anyways, I know first hand ENTJs can be charming, wonderful people. But just like everyone else, they have unhealthy behavior. I think EXTJ's unhealthy behavior seems just a little more "In your face" than others, although that's obviously debatable.
