Anyway... I think the enneagramm is a quite helpful tool. Nevertheless I think instincts are not the most beneficial parts of the enneagramm. I for myself feel all three instincts in me even though one might be stronger than the other. If I observe other people I come to the conclusion that people who I consider average to healthy don't have a very evident "inferior" instinct.

But that's just my opinion on the subject and I know almost all gurus would probably disagree.
