I'd wager that most people experience each of the 9 enneagram fixations and passions at one point or another. Yet, the enneatypes characterize pervasive patterns of thought which define these fixations and passions as persistent for each type, respectively.

So how does, for example, a 7s gluttony differ from the gluttony of other types? How do you think your thought patterns in regard to the enneagram truly differ from others'?
