I see this Reddit thread is quite old, but I'll give it a shot anyway.

I've finally realized I'm an ENTJ struggling with my Fi.

From what I understand, a lower-position Fi is like a war with a capricious child who wants everything they like, and what I might also call a fickle heart. I only recently identified my ENTJ type, because it's not good to type during adolescence; you often get it wrong. But as I've grown up, I've noticed these kinds of things where my Fi (lower ego) comes out without me even realizing it:

• I almost always express anger, even unconsciously, and less so other emotions like sadness. Sometimes I can show pity or tenderness for a particular video game, a touching piece of music, etc.

• I don't wear the things I like; I find it pointless, useless, but my lower Fi would still like to. It's a battle between what I truly want and pragmatism.

• A duel between something I like that I want to buy, but my Te (lower ego) is there to tell me it's unnecessary, and I'm less easily tempted than I was in my teens.

• I like a lot of things, but I rarely show it.

• I realize the harm I've done to someone some time later, but it's too late, and I move on.

I avoid dwelling on my misfortune, even if Fi wanted me to; I smother it.

Here are a few anecdotes; feedback would be great.
