[INTJ] The vessel must be kept in optimal situation to sustain a power hungry brain. I usually fully withdrawn when I'm on my bike, those hours I have business plans and many things in my brain, except biking.
There is an ache in my brain pops out every split second that Catie Wayne actually looks like boxxy and my brain starting to guess if they are the same person which I'm unconsciously refusing to do so.
It sounds like Se when you're talking Fi, or at least a mixture of both. INTJs are all about priorities, and normal people fixes their day to day struggles before internal happiness build up.
I think Fi cannot mature alone in INTJs' minds, when Fi kicks in they start to realise they need happiness, the next moment we already know they need to fix day to day problems, and then Se will start tingling. These two functions are really tied together.
