I do get that Je can bring a certain will, but it seems from my experience that Ji can also be a very powerful force, a catalyst for change, disrupting Je plans and bringing to light the flaws in Je plans, with a will that can not be denied. I also find Te in the Dom or Aux is more likely to be the steamroller than Fe, but that might just be my biased perception.
Now this part I can completely relate to myself. I easily can see the direction everyone else is going and how it will turn out, which variables are strong or unlikely, and the end result becomes very clear, and I am pretty comfortable doing that.I know I suck at seeing how to put puzzle pieces into place for myself in order to lead me to an outcome I desire - partly because I have trouble defining what outcome I want in the first place and partly because I can see so many variables along the way that could derail me, so I find it near impossible to make a choice. But what I can do is hear what people have decided and know what outcome is most probable from that point forward. Like, in a "No, that's going to be a bad idea" kind of way.
I completely suck at doing this for myself these days, partly because of that uncertainty about what I want for myself, and partly because of past experience of envisioning a direction, getting exactly where I wanted, and still being unsatisfied with the result.
