Here is what I know - I've tried to live in my world through Fi - Te alone. Screw all the rest of the functions. It didn't work.See, it's this kind of unsolicited advice that (at this point in my life) gets me irritated with Ji-doms.
You are allowed to be critical of my extrapolation, and you're right, I'm not offering all of the other supporting evidence I have to back up that advice, and it seems like I offer nothing but my own opinion and am not proving it with any perceptual data. So you're right to question it. And yes, everyone is on an individual journey. Of course, everyone's trajectory is unique.
I hear you - it's about credentials. Perhaps over time I'll be able to offer something more palatable.I suggest you spend more time trying to understand better and less time trying to give INFJs some supposedly urgent message about what we should do.
eta: Hey you did Fe me! Very nice.
