I can start with myself.
I’m primarily fixated on understanding myself. This entails investigating and attempting to apply various psychological theories to my own situation. The end goal, as far as I can tell, is to form an accurate explanatory model of my behavior.
I’m not sure which functions this corresponds to. It seems like it has to do with phenomenology, so maybe Ni. It also seems related to identity formation and self concept, so maybe Ti.
What’s your fixation in life and how do you connect it to cognitive functions?
I might want to revise this later on... I've been spending the most time trying to release ownership over every aspect of myself and every aspect of my mental world.
To kind of get a small sample... say someone says your a 'bad person'. You don't want to believe it is you, but can help feeling like it is you. You realize that you felt that someone else a 'bad person' in the past. Someone you had an emotion dispute with. Now you rethink your interpretation. Now you come to a new grand realization. Which partially involves you realizing how he's not so different from yourself. Now you know that the person who says people are a 'bad man' is enabling himself to be affected the same way you were. As he/she is projecting what's already in his/her mental world. In a nutshell you are own mental world. You are what you call other people. For reasons involving matters outside of CT and topology I am a 'faggot parasite' at this current time. What are you?
I'd say this likely uses Ni and some Ti both lead by Pe. So yeah my fixation.
My fixation was Fi, a year ago, when I tried to understand my identity and form my self concept. I can relate to EpicEntity's and SupahProtist's answers. I can say I do it nowadays as well, lowkey, it's not fully developed yet, but I suddenly changed my concentration area (I can't say it happened suddenly, I had to reevaluate a lot of things actually, I just realized I didn't have much time for 100% concentrating on that).
For now, I have a lot of concentration areas, a lot of life fixations and dedications, I should say. I'm a student, actively engaging and working with people, I read a lot, not only academic requirements but I enjoy fiction a lot. Also, non-fiction, well, I just enjoy reading and thinking about things. Also, reading gives me base for my work. I even worked as an astrologer, because I know a lot about tropical astrology and I have improved how I read natal charts and synastries. Actually I wanted to improve my writing skills, my fantasy, my imagination for writing my actual collection of short novels. I have very specific views on astrology, I think it's rather an art and a wonderful field to improve your artistic skills. But then I stopped making charts, I decided it's enough and have started writing actual short novels.
So, I'm 24/7 thinking about how to USE my knowledge and CREATE meaningful things. I'm widening my social circle and making connections, possibilities... I'm thinking and trying new things, taking pictures, adding words to my CV and general experience... But I'm not actually into working for specific goals yet. I'm looking into the future, but without any specifications. I'm living for now in the present moment and acting on what I decide is meaningful, I mean, useful and fruitful.
So, I think my ego fixation is Ne. As a lead function, this fixation makes me feel my natural being. I do things that are effortless. But not enough for understanding my self concept and this fact makes me a bit sad, but well, not sad enough to change my direction, yet. I try to adapt nowadays and circumstances around me also require flexibility. I think I changed my fixation from Fi, because it was not allowing me to stay in tune with many other things in my life. But learned a lot about myself from my Fi fixation, I created my own compass that I feel will be renewed if needed (still leaving options open for myself lol). So yeah, that's the declaration of my ego fixation and don't forget to like, share and subscribe! 😝
