@Starry One reason, why I typed myself as a 4 in general is that I'm a really introverted extravert. I have read Jung, so I can safely say I'm an extraverted intuitive. I know that many ENFP 7s also see themselves as more introverted extraverts, but here's why I believe that I'm an ENFP 4w5:
1. Search for identity: The only reason I got into MBTI and enneagram was that I wanted to know who I am. I don't know why but having a connection to my identity satisfies me. I also have a strong connection to things I identify with. In my home I want to be surrounded by things, that mean something and have value to me. Before I buy something like a table for example, I consider what impact its colors, its form will have on the environment. I express my personality with it. I won't buy it, if it is made of Italian Mahagony because it has to symbolize a place I feel connected to, like a birch which needs a lot if water (I like the rain).
2. Romantic vs. Realist: I have an ENFP 7w6 (selftyped) buddy and he is a perfect example of his type. He is cheerful, he is an entertainer and he's also practical. I appear far more reserved and impractical. What I also noticed is that he hates it when the sun isn't shining and it's dark and moody outside. I like that. I always felt kind of attracted to melancholic things (Tim Burton movies, the zone Gilneas in WoW, artists like Lykke Li and Fever Ray). My desktop slideshow mostly has pictures of foggy autumn forests, dark moonlight, etc...
3. 4w3 vs 4w5: I simply type myself as 4w5, because I can relate to 5 and not to 3. I am withdrawn, I am introspective and I am an extravert, so why not?
I already posted the link before, but this article helped me a lot with finding out my type. http://theenneagram.blogspot.co.at/2...fying.html?m=1
