Unlike the Myers-Briggs, the Enneagram offers insight not just on what you're like, but how you're most likely to make unhealthy choices (and how to make healthier ones). As I read about each type's unique motivations, I started to understand that I am not really the baseline for normal. (Yeah, that came to me a little late.) When other people made choices that didn't make sense to me, I finally began to think, "they must have different needs from mine" instead of "what an idiot!"
This weekend, I went to a workshop taught by Michael Naylor on the wisdom of the Enneagram. For each of the types, Michael recommended a week-long exercise of abstinence from that Thing We Do that keeps us from spiritual growth. Of course, that Thing We Do is also the thing that helps us dodge the relentless Inner Critic. (Nobody said it was going to be a fun week.) In fact, it's pretty reasonable to talk about some type-specific habits as addictions of personality. For some it might be helping too much, for others it might be isolating themselves.
For still others, it might be refusing to commit when there are so many possibilities and options out there.
Wait-- what? No, you don't understand-- if I did that, I couldn't do lots of different things!
I'm trying it this week. If I perish, you'll know why. I will have clawed my way out of my own skin to avoid being trapped. I'm going to try to let you know how it goes.
