I suppose I'll have to get the ball rolling... My Enneagram type is 5, and while I don't fit perfectly into any one Myer-Briggs type (it's not so much black and white as it is which characteristics are dominant), I am most like an INTJ. Both are stereotypically known for being knowledge-seekers, who will learn everything they can.
When I learned I was these personality types, it really only made sense to me. I've been told many times that I'm an information sponge. This also explains my natural ability to make jokes by tying similar ideas and words together to make puns (for example: if a Caucasian Republican gives someone a useless item, is it a white elephant gift? Doubtless someone is gonna get triggered at that). This also explained why, when I was five years old, I burst into my mom and dad's room crying, "I don't know everything yet!!" That statement pretty much sums up us type fives.
However, so I don't seem like I'm bragging, I will list some downsides of being a 5/INTJ. Firstly, because I am an Introvert (that's what the I stands for), but also want to share my knowledge with others, I'm often torn in two over whether I should speak up or not. I usually do. However, because I have a bad habit of speaking faster than my brain can convert ideas into words, I occasionally don't get my ideas across accurately. And because I'm a 5, I often act fairly stoic (since 5's act based on logical thinking, rather than emotions), which some of my friends don't necessarily appreciate.
So there you go, my answer to my own question. Can't wait to see y'all's responses!
