You remind me of the wife of an LII friend of mine. I never tried to type her, but let's walk through the video.
You seem extroverted. No pauses to look inside yourself when you are talking.
Socially awkward with few friends growing up.
Can get into conversations with people easily.
- extroverted.
Can't stand immature people.
- want to elevate yourself above the average. Fear of appearing incompetent or inadequate.
"I seriously can't stand it, because, it's...I don't know...they're so mean. How could you be mean to people?"
Gammas hate mean. It is the worst thing a person can be. Alphas also hate mean people.
"I kind of went on a tangent. I do that often."
I do this a lot, too.
Impressed by people who work hard.
- business orientation.
"I'm mostly focused on stuff that I'm interested in"
Doesn't study as hard as some other people, just reviews material for a few minutes.
- intelligent, but I did this in HS, and I think a lot of smart people do this, too. Poor study habits will force a wake-up when you get to uni.
"It actually makes me sound like a stupid person, but I'm not"
- smartsplaining.
"I manage my grades. I'm actually doing quite well."
- "manage" grades
"I was never really confident in myself. Ever."
"I appreciate when people bring up things that I'm good at"
- seeking input, because not confident of values. Weak Fi.
"I hate conflict. Why can't you guys come up with a compromise?"
- Seeks to provide impartial, rational solutions.
"People in a state of extreme emotion cannot think straight. They will not be able to be rational-ized, they will not listen to any form of rationality."
- values Thinking over Feeling.
"I over-think things a lot. I try to find out the meaning of things, especially in their actions and words. Like, do they hate me?
- unsure of social norms
"I'm going to end this video. It's eleven minutes, I only have fifteen."
- very time conscious, very Ni.
I think you are LIE-Te. You might also be LII, but your sense of time makes that less likely. Also, you never mentioned your health or comfort, so low to no Si.
One thing you should keep in mind. I'm usually wrong about everything. There are other people on this forum who are much better at typing than I am.
