Last night I couldn't sleep because I was trying to figure out how focusing on some IEs extensively has worked for me in the past (before I knew Socionics and what IEs are).
So I selected some "mental hacks" that I have used extensively during different stages of my life to achieve different results for different situations.
I realized that there wasn't a single one that I could apply to all aspects of my life (That should be obvious btw)
So here are some of them and how I think it conflicts with the antithetical approach for each case.
PS: Notice that if you switch function X so that Xi >> Xe becomes Xe >> Xi and vice-versa, you get the opposite result that came from the first approach.
Be sincere - Fi. Too much of it causes loss of emotional sensitivity (Fi>>Fe).
Be funny - Fe. Too much of it causes loss of morality and authenticity (Fe>>Fi).
Do the most important things first - Te. Too much of it causes loss of logical structure (Te>>Ti) in work
Innovate - Ne. Too much of it causes loss of meaning/purpose (Ne>>Ni).
Keep record - Si. Too much of it causes loss of intellectual production (Si>>Se). conquering new information vs maintaining information.
Study it until it gets obvious - Ti. Too much of it causes loss of efficiency (Ti>>Te).
Become a better [person] - Te. Too much of it causes loss of internal consistency (Te>>Ti)
Use Route learning - Se. Too much of it causes discomfort (Se>>Si) and mental fatigue.
Take breaks - Si. Too much of it causes too much comfort (Si>>Se) and loss of endurance.
Change subject to keep things interesting - Ne. Too much of it causes loss of purpose (Ne>>Ni)
My conclusion is that I can improve the efficacy of my results by adjusting how much "extroverted or introverted" I need to be depending on the environment.
