I had poor Fe skills as a child. I kept other kids at a distance with my intellectualism. I thought I was INTJ, so I tried to go hardcore on the Te-Fi axis, but that caused:
1. arguments with other people
2. pressure to take over and do things my way
3. a never-ending stream of criticism of others in my mind
4. defensiveness of my own values.
It was not a light and happy place.
I was disgusted at the idea of being an INFJ. What kind of wussy person was that? Someone with FEELINGS instead of LOGIC? No, not me.
Well, guess what? Ti is intellectualism par excellence. Te accepts outside facts in order to achieve quick, efficient results. Ti is the function that has to understand everything before it believes. Ti is mental strength. That is not wussy.
As for Fe, it's fun. Way more fun than Fi. Now I can transfer my hardcore values into the category of Ti and keep them safe, as in, "This is my truth, and you will not move me. I know how this works."
My feelings are used for creating harmony or avoiding conflict. I play with people. I'm actually fun to be around. I have lots of friends. Hey, this is way better. I'm not stuck on heavy values anymore. People have their own, and I have mine. Just flow with it.
Ultimately, I think it is important to learn to use all functions in all orientations. Currently, I'm working on tamping down my Ni in order to enjoy my Se and get a better read on reality. Also, I'm trying to remember my Si lessons and recognize multiple Ne opportunities.
