I'm an Enneagram 2 with a 1 wing and what appears to be a fairly strong line to the 4. (If you're new to this Enneagram stuff, check out the information on the enneagraminstitute.com website. It takes a little getting used to, but it's well worth the effort.)
I had a workshop about Enneagrams a few weeks ago. I am a 5 with a strong wing to 4 and a line to 7. When we were first asked to guess our types based on a one sentence description of each, I thought I might be a nine, because I am laid back and tend to avoid confrontation. But I found when he described each type is that I am without a doubt a 5. He said that 5's tended as children to be the ones who preferred to stay in their rooms and read instead of going out and playing with their friends. I took the material he gave us and showed it to my parents. They can be assured now that I wasn't a loner, or a hermit - just a 5!
It's great to see you guys using the Enneagram stuff. Not only is it useful for self-discovery, but it's one of the best tools I've ever found for team building. When you are in a leadership position and you're aware of the behavior patterns that people tend to rely on, it's much easier to help them find a path on which they can succeed.
