There are a great deal more than nine types in the enneagram. If you factor in a type’s wing that number instantly grows to 18. There six variants that will raise the number to 108. This is considered before speculating on other factors such as tri-fix, triads and your level of health.
I think what the personality type system does is attempt to oversimplify which is why many follow it. Yet even then most are not appreciating the fluidity of the system, and considering that Jung never referred to simple dichotomies. In fact, Jung was against using his work to create full blown personality typing. It is my understanding that he expounded on Freud’s work to determine that there are more than just extroverted types (notice the different spelling) and subsequently realized that not only are there extraverted/introverted types, but for some reason people use the attitudes differently resulting in his functions.
The enneagram is highly complex, and as such anyone who has a low threshold for complexity will not tolerate following the system. I tend to step back from the enneagram for several years to digest what I have learned and then return. When I step back from personality type, it’s usually because I have become bored with the system until I find another component worth learning.
