I have a friend who I'm having the same delimna with. the problem is, he uses Ne, Ni, Te AND Ti and he's great at all four of them (he took the cognitive function test and scored perfect on Ni, Ti and Te and almost perfect on Ne). his introverted and extraverted feeling are about the same strength and his extraverted sensing is also very high (but only because of years of hip hop dancing 5 hours a day, anyone's would be). he seems like a P because he is really ridiculous and has a very perverted sense of humor (as an ENFP, I never thought I would meet my match in perverse humor until I met him hahaha). he also loves talking about ideas we spend a lot of time talking a million miles a minute about many of them (this screams Ne to me, I don't fathom a non NP could keep up with this at all). he also seems J tho because he is heavily success bent and goals oriented. we've guessed an number of types including ENTJ, INTJ, ENTP and even ESTP (although I am pretty sure now that he's not S) he's also a very intense problem solver. when I'm around him, I use lots of Te along with Ne which makes for extremely intense conversation (I wouldn't have it any other way tho, small talk is boring as hell to me). I've heard that ENTPs tend to exhibit this characteristic to tho, and often times look like ENTJs, so I lean towards P) in fact, most people think I'm ENTJ because I am extremely direct and assertive (although I'd like to think I come across as less forceful than most ENTJs. I don't hold this against them tho, most ENTJs seem a lot more forceful to most people then they really are).
