When I took my first MBTI type in the summer of 2011 it really opened my eyes.
But a lot of the problems and questions posted on this forum really don't resonate with me. In fact, while I may be very social I don't make friends very easily and have always felt an odd alienation from most people.
While this could be explained by being surrounded by sensors, I didn't like this explanation.
And then I learned all about the Enneagram.
A lot of the stereotypes thrown around in this forum can be easily explained more effectively by learning the enneagram.
It really helped narrow down my motivations as an individual. I finally settled down on my core type and tritype which helped explain a lot of my own issues. It's not a perfect system but a typographical map of my mind is better than nothing.
It definitely seems complicated at first, but start by reading every type and understanding how the wings work. Pick 3 types that you relate to the most in each triad (head, heart, and gut). Then, dive in to the instinctual variants.
