It happens naturally with age and maturity. I think late teens and 20s is when you really start to hit your secondary function. Introverted feeling is harmonizing value systems....basically just means you start to figure out what's important to you and react accordingly. For example....someone bad-mouthing your friend. Before Fi really develops, you don't really know how to react to that.....it just makes you uncomfortable. After Fi develops, you turn into a raging lion and tear the head off the attacker, making them feel and squirm like a 2 year old getting scolded. That's only one example....but you get the idea.

I remember hearing something from someone at the other forum, who'd been reading some books on this stuff. Unfortunately, that forum was hacked and the entire thing deleted, or else I'd be able to give a more complete answer... but from memory, I remember one of the exercises you could do to work on your Fi was:

Write down 5-10 things which are important in life, and then rank them from most to least important. Then write down 5-10 things which you find very unimportant, and try to rank those in order of importance.

But yeah, lys is right. Imo, you'll probably get there when you get there... so there's no reason to try to rush development.

The book he took that exercise from (I think) is called "dynamics of personality type: understanding and applying Jung's cognitive processes" by Linda Berens. I know there's stuff on all the cognitive processes, and what you would do to develop them, in there. You can actually see a good chunk of it for free on Google books.... but sadly not the parts that discuss Fi.

huh? Wouldn't that sort of reaction be interpreted as extraverted and not introverted? If you direct your feeling outwards, such as lashing out at a conflict of values, that's not introversion.

>.> The process of identifying a value or sensing disharmony is introverted and entirely unseen, but it also demands action. General discomfort to the undeveloped Fi just makes you want to leave the situation.... The values become more important and pronounced as Fi develops, making more direct action more likely.

Extroverted feeling is more affiliation than harmony....relating to others via feeling. They adapt their behavior to maintain peace and respect....but harmony isn't dependent on their own personal values.

My INFJ friend (INFJs having the same order of functions just all the introverted and extrovertedness flipped) put it this way: I'm a Peacekeeper and she's a Referee.

Thanks people, it helped me a lot
