I could relate to several elements, the like/dislike being noticeable, the strong willpower, the taking the world as-is and not living in a fantasy world, taking what I like/value in the real world and applying to myself in own way.
Re 'not understanding potential', I am not sure the presenter really understands the reasons for this; it's not 'not understanding' the potential, it's the not finding it necessarily applicable to the here and now / my actual motivations and how I operate. Also I'm not interested really in what potential other people see in me - I want to discover and unwind my own potential, and learn that for myself. I don't want to be told what I should be aiming for, iow -- that's part of my own self discovery. (Or, it might be akin to this sort of internal reaction: 'Well that's nice and interesting that YOU think I have X potential, but I am not focusing on that at the moment, and it's not of primary importance to me right this instant. And, I may decide to go down a different avenue than that.' It also brings to mind my upbringing, of how 'intelligent and smart and good at math and science' I was, and was encouraged to go that route because of my 'potential', but simultaneously from another direction I had 'so much potential at the piano'; meanwhile I was trying to find my OWN voice amid these adults telling me the potentials they saw in me, and getting lost for a handful of years in the process)
I thought the video was decent, but, I think it's important to note she is 100% socionics influenced, and socionics has some fairly hard lines in terms of what types 'can' and 'cannot' do and do and don't do (and there are some differences in how socionics views the functions vs mbti). i.e. she mentioned, 'Fi doms won't notice the atmosphere around them, they probably won't notice someone laughing'. Well that's b.s. imo.

There were a few other elements like that that just seemed kind of extreme and not universal.
