Last time, I promise. I am almost done getting this stuff, and I think I have the right way to go about everything. It's gonna be a little different, and functions aren't quite exactly the same, as I think some types get screwed by not having the "talented" functions in the current system, where I haven't seen talent and type correlate in the real world (unless you see the talent first, and give them a "talented" type by that, which I will never fucking do, ever. A good friend of mine is INTj and could easily beat the shit out of everyone here. Another friend is INFj and could outsmart anyone I ever knew, ever.)
The functions have alot of flexibility. For instance, Ne is going to be able to "do" Se and Ni, only it isn't really going to be a major goal of that person, nor is it going to be the way that they want to live life all the time. People use thier main functions because they LIKE to, not out of fear or any other such bullshit. (Fear isn't anything stable anyway, you can't build a personality out of it, because it doesn't really exist, you can only have fear when you aren't doing anything.)
The dual seeking function, and hidden agenda can help to completely elminate the need for "flexibility" of the first and second functions, letting the person continously focus on thier strong points, and only just subconciously "accept" information on these functions.
This whole thing is a Ti-sturbation, but I figured, what the fuck, might as well post the shit. Well, here. (I will go into detail on the functions in the next post, but most of this crap isn't anything you haven't seen before, it is mostly just me trying to explain to myself how this shit comes together. Yeah, I'm a dumbass, so sue me.)

Physical Influence

Physical Completeness

Mental Influence

Mental Completeness

Rational Influence

Rational Completeness

Personal Influence

Personal Completeness
Influence: Energy expending, seeks objects and people to act on or take in information from. Focus is on the objective qualities, and deals in information that doesn't need to be simplified.
Completeness: Energy saving, seeks to take information and simplify it in a condensed and personal matter. Focus is on things that are directly important to the person, and the subjective qualities of that information.
Physical: Things that are tangible to the senses, obvious to others or the self. Exists to the Senses. (Direct, Apparent, There)
Mental: Things that exist in relation to memory and time, in an abstract reality. Exists to the Mind. (Indirect, Ineffable, Hints)
Rational: Things that are systematized and able to be proven or disproven. Exists to Everyone. (Controlled, Precise, Determined)
Personal: Things that are personal and unable to be exactly determined or proven. Exists to You. (Moods, Attitudes, Emotions)
Physical and Rational can be anchored to something real (giving them an impersonal quality), and Mental and Personal are too fuzzy to anchor exactly (giving them a personal quality.)
Physical and Mental are traits or states of being, and Rational and Personal are values or actions.
If your thoughts are mostly directed along the lines of determining and using your own traits, you must have an underlying value system, and your actions and states of being indirectly follow from this, and are usually unconcious.
If your thoughts are mostly directed at your own state of being, you must have methods of action that you conciously use, and your trait perception and values indirectly follow from this, and are usually unconcious.
Influence (expendature of energy) and Completeness (conservation of energy) are obviously at odds.
You either look at the world "as it lies" (Physical) or "in your mind" (Mental). One of these will be the "fall back". That is your type.
You can either consider the world as "existing outside of you" (Rational) or "how it affects you" (Personal). One of these will be the "fall back". That is your type.
Everyone can do all 8 of these at any time given a little thought. The difference lies not in "strength" but in "comfort level".
Obviously, the rest of the Socionics shit applys, and I don't gotta go over it...
Extroverts seek influence or the potential for influence mostly, and Introverts seek completeness and things that contribute to completeness.
The "Hidden Agenda" is the most tenuous Extroverted Function for an Extrovert, and the most tenuous Introverted Function for an Introvert, and needs to be satisfied for total outer/inner wholeness.
The "Dual Seeking" is the function that needs to be satisfied in order for the dominant function to return to it's most complete and natural state, and contributes to completing the inner wholeness for an Extrovert, and the outer wholeness for an Introvert.
