Assertive triad types, notably 8 and 7. I don't relate to E7's motivation at all and those are types I've never considered for myself. I do get 7 is technically a ne-ish type and I relate and value worlds of ne, so with this being said, maybe it weird that I relate to being very ne and being very positive outlook type but not 7. Being a more or less-singleminded person when it comes to my goals and personal projects. I never understood 7s and the spontaneity, and general impulsiveness of the id types/assertive types. 7s are also quick-moving and like to take life at a fastpace and I'm a turtle. I'm much more in my head, and withdrawn, and on the cautious side to be a 7. And I'm a person who needs a lot of recharging and gets drained easily which contradicts a lot with E7. I don't get 7's need to experience all at once. While I'm an open-minded person, I need to pace myself before going from one thing to another.
On paper, I actually think I understand 8s motivation and basic fear to an extent, and I relate to being independent, having a rejection aspect. While I understand this attribute of 8, I have always understood that I'm the most un-8 person who ever walked the earth getting into ennea. Rejecting weakness altogether to the point of frowning upon those who show it and being comfortable with anger, challenging people, taking enjoyment in it is very alien to me.
I can understand wanting to control your own situation, but controlling other people and everything is something that's a headscratcher, and going out of the way to confront people. The choleric temperament overall is very alien to me, and that goes hand-and-hand with 8. It's like their on a whole other plain of operating than I am.
