I was practicing working out cognitive functions of the types the other day and trying to acctualise how the cognitive functions realate to MBTI type. I am an ENTP with (obviously) Ne Ti Fe Si and I was looking at the INTJ profile and noticed that they have the inverse of my functions but in the same order, Ni Te Fi Se. Now I don't know If this is already a well thought of thing but after reading the INTJ descriptions a few times I realised that I have always in a way tried to see myself as their type. (the detached unemotional thinker who can sit isolated without discomfort and think and actually follow through). I have read that a lot of attraction comes between the opposites of a function (e.g Ne to Ni) and I got the idea that because all the functions are opposite in this way, that INTJ is my idealized self or the person that I want to be.
I went to my good ENFP friend and asked her about my INFJ friend that she had met a while back, and she pretty much told me that she thought miss INFJ was living the life she wanted (a dedicated musician who sings almost directly from the heart) and she always saw herself as what The INFJ truly was. My INFJ friend also really liked the ENFP but I haven't asked much about it to her.
Please if anyone can confirm or contribute to my hypothesis it would be most helpful
