I don't know what enneagram is but I can tell you that I have been an introvert my whole life. I very rarely ever talk, go anywhere or have any friends.
Yet I am also awakened so can exemplify what qualities I choose if need be.
For SteemFest I was without a doubt flaming ;-)>
The enneagram is a very cool personality system based on an ancient Sufi symbol, it has 9 main core points but can be subdivided down to like 46 different types or more. The best book on it is the "Wisdom of the Enneagram". I use it a lot to understand myself, to seek my pure being free of ego, as well as to understand my friends and family. It helps me accept people with all their different takes on life. I'll probably do a post on it at some stage as I love it!
Hmmmmm.... 4 might still be about right for you, check it out. The 4, or "romantic" is : a "Sensitive, Introspective Type: Expressive, Dramatic, Self-Absorbed, and Temperamental". One of my brothers is a four, he has a very fine-tuned sense of aesthetic and likes to differentiate himself, that's why I said it as you have such a specific aesthetic to your style!
Anyway, don't mind me, I guess it could be quite rude to psychoanalyse people I don'y know on internet networks! I don't mean any harm by it!
