There seems to be something really special about this type. My old roommate was one. It's my head fix. It's supposed to be the *most* human of all enneagram types. They're the least know-it-all of the head fixes and I think that's due to the fact that they have the least confidence. In a way they are their own worst enemies. 6w7 is supposed to be one of the most likable type. They consciously make themselves seem nonthreatening and unimposing.
What are your experiences like with 6w7s?
