So how do you describe your use of your four primary processes (in 1-3 sentences for each)? How does it fit all together? It's easy to find a blanket definition for each function, but I'd like to hear how each individual describes it in the context of their own world.
As an ISTP, I would define myself as this: I see all the possibilities in the present (Se) and partly in the future (Ni) while my primary Ti breaks down these opportunities to determine the best option. Fe has a very limited supporter role when making decisions.
For each Function:
1st (Ti) - I use Ti to break down the opportunities and information at hand. If I were hopping along stones in a river, my Ti helps me balance and directs me to the next best available stone.
2nd (Se) - I use Se to see all my present opportunities and gather any information I need to make decisions. If I were hopping along those stones, Se sees all the stones directly in front of me.
3rd (Ni) - I use Ni to gather just enough information to prepare for making plans in the future. Instead of gathering all the information available, it only gathers the most important information or imagines the most likely events. Ni is my peripheral vision in my river setting -- It zeroes in on the most likely stones I'll need and, in some ways, Ni plays a small balancing/directing role too.
4th (Fe) - As mentioned before, Fe has a supporter role in making final decisions, and is very limited (but still being developed). I use Fe when Ti is not enough, or when I feel like the decision at hand involves important people to me. I can't think of how Fe would fit into my river setting (see how important it is to me? ) ... maybe try to steer clear of any people around me (I didn't even imagine people at first in my scenario...)?
