Yes! Well, I have to admit, my favorite self-discovery tool as of late is the Enneagram of personality as studied by Don Riso and Russ Hudson. I'm even starting my own discussion group on it. ^_^
The Enneagram is one of my favorite tools, also. It has a complexity that most systems do not. It incorporates not just a type, but wings, subtypes, direction of integration, body centers, etc.
How do you see the focus on Don Riso/Russ Hudson compared to Helen Palmer? Are you familiar with other perspectives on the Enneagram?
I have read and am in the process of reading most of the Riso & Hudson books, not yet started on Palmer. From what I have read of excerpts, however, my impression is that Riso & Hudson is much more reliable as an accurate interpretation of the system, although Palmer does have some excellent insights, especially on certain types like 4s.
