It was eye-opening and scary how much it helped me realize about myself. Everything about me just fell into place. I think the core aspect of my personality had to do with wanting to understand everything (a.k.a. why I am a know-it-all and a nerd) but at the same time having a tendency to detach myself or isolate myself from the world around me.
Did it do the same for you?
Yes and no.
I have only taken the Enneagram that one time during high school, and by that time I had previously done the MB two or three times and had received INFP. And so in that sense, the Ennegram results matched up decently with those for INFP, and so it wasn't necessarily new things for me. But, at the same time, my Spirituality teacher paired the test in conjunction with a unit called the Shadow, which basically talked about the raw, primal, and deeply creative sides of the human soul. To that end, I appreciated the results of the Enneagram even more, because it really made me realize how in touch I was with my shadow.
So, I guess what I'm trying to say is that the details weren't necessarily new, but my perception of their depth certainly changed. I never realized how intrinsic these things were to the very core of my being.
For me, self-knowledge has always been a priority, because I don't know who I am, to be honest with you. So it's scary and yet exhilarating.
