This question might be odd or ridiculous, but are there certain things you can do to increase the usage of certain functions in everyday life? Like a certain "brain exorcise" or something of that sort?
I certainly believe so. Here are some ideas I've got.
For strengthening Fe:
1) Write down three things that some people you know like and try to think of three more on your own that would suit each one.
2) Have conversations where you focus primarily on the other person and how they are currently doing. If the other person is similarly Fe-wielding, you will be naturally engaged as well.
3) Smile at everyone you pass on the street (not too big or else you look crazy ). If feeling especially daring, also greet with good morning or good afternoon.
4) Think of an action someone takes and how it conveys one or another message to everyone else.
5) Visit more often with relatives.
6) View yourself and all others as part of a broader context. Within this broad context, [social] order is what matters most. Basically, no man is an island. All individuals work together towards a greater [common] goal.
For strengthening Se:
1) Go for a walk, write down which parts of the scenery were most eye-catching, describe them in detail (bonus points for similes). Alternatively, replace walking/scenery with music/notes or anything/scent. The most convenient thing about Se is that it can be used anywhere on anything.
2) Selective coloring in Photoshop . It can be simple, but still a great way to exercise Se: pick the perfect color down to the slightest shade, take in the entire picture and notice even the smallest effect on the overall balance, mix and match until you find a way to make everything pop!
3) Read a book (hell, even read the forums). This alone is exercising Se because you are processing the details of the external. For bonus points, also judge your comprehension time; how many times did you have to read it before really taking it in? Note: Simple reading is fine. If it gets too abstract or theoretical, it is Ni/Ne instead of Se. Your comprehension doesn't have to be counted in depth of thought as much as it is: I read this, the words are now in my head, and they are not mush.
4) Go to a public place, take in the energy, and then describe it in detail. How does it affect you physically, mentally, emotionally...?
5) Set aside some time for things that depend heavily on action, reaction, and interaction. Bonus points if you also need a lot of coordination. Instead of chess, play a card game like Speed. Instead of Pac-Man, try Dance Dance Revolution. Instead of the carousel, go to the bumper cars.
6) Do anything physical. It does not have to be high-energy, you can for instance try yoga, twister, or form your own mini conga line. How's it feel to really inhabit your body?
For strengthening Fi:
1) Think of three things that are so important to you that you could almost never bring yourself to compromise under any circumstances.
2) Think about what is the most meaningful aspect of life, or more personally, yours. Ask yourself why it is so.
3) Try to make at least one decision each day based on what is most important to you. Please note that this doesn't equal what makes you feel good (that is probably more Se ). You can use your emotional reactions for information, but a large part of Fi lies in analyzing and exploring those reactions to get to the core root of the matter, which is to find what is important in that instance, and how important it is. Typically, the level of unbalance/disharmony you experience is parallel to the level of importance within the value you face compromising.
4) After you make that decision, consider whether you chose to follow said value or compromise it. Describe how you subsequently felt after either. If you chose to follow the value after all, did you feel a nearly ineffable sense of internal relief or balance? Said sense is probably what makes Fi so difficult to translate into words.
5) Think of the Golden Rules (i.e. "Always say please", "Love thy neighbor", etc). Ask yourself why they are important/unimportant, right/wrong, good/bad, and decide whether or not you will follow or ignore them.
6) The next time you hear about a problem someone is having, a misfortune they are encountering, a sadness they are enduring, or an anger they are experiencing, try to put yourself in that person's shoes and thoroughly understand the whys and hows of that situation. Note that you don't have to feel sympathy, pity, or make excuses for them. You just have to step outside of your box. Note that this empathy as opposed to sympathy is often what keeps Fi-doms almost naturally inclined to high respect for boundaries.
For strengthening Ne:
1) Make one of these lists on your own
2) "How would the world be if ____"? One of my personal favorites is, "What would change if most of the world's cultures were matriarchal?". Think of change for the sake of change.
3) Go out of your way to have your views and perspectives challenged and expanded. Be open to any and all.
4) Always look for more; try to view the potential of an idea rather than just the idea itself, and work your way into synthesizing a broader, greater whole. The next time you encounter an idea, consider its deeper implications within a broad context.
- describing something in several different ways, such as a chart, graph, list, words, etc.
- take some everyday task and think about how you could streamline it to make it more efficient. what is unnecessary or redundant?
- taking a long, confusing forum post and reorganizing it to be more clear.
- look at your "to do" list and see if you can group things together to make them easier - like if you have to go on errands, try to create the most efficient path
- conduct an experiment
