My poor Ti, way down in the proverbial basement of my soul is just starting to see the light of day (from the safe, non-interactive confines of his bunker). You're absoleutely right, it's tough. I have been going through a bit of an identity crisis whenever I try to use Ti...it's like plotting an outlier on the graph and suddenly realizing that is as much a part of you as the rest of the points that you used to combine to picture yourself. You start to play a game of "connect-the-dots", and to reconcile those that don't seem to simply fit together, you have to create a much more complex self-image...one that is both feeling and rational and and you have to learn which should lead intentionally depending on the situation.
So far, i've noticed Ni/Ti comes in when I must emotionally disconnect myself from a difficult "people" situation that I have to endure for awhile (I think...I might still be foggy on the concept and if I am incorrect, please feel free to demonstrate the right way for looking at Ti). Annoying or clingy roommates for instance--when someone fails to give me my space when I need it, or seriously fails to be curteous in some huge way, I become Fe dishelved. I've found that if I "back away" from my feelings, I am able to unoffensively guide someone into following social protocol that they didn't know was there to follow before. Their lives are improved because they make more friends and offend less people--and that includes me, so my life is too.
My job is to bless the world, not curse it. My job is to leave the world a better place then I found it, not to cause it more harm. Yes, that's the typical NF creedo and much more so for the NFJs, but how can I help the world if I am constantly offended by it? How can I build a bridge when I can't emotionally deal with the situation? At the very core of maturity is the ability to see things from another prespective then your own--to be balanced and able to handle both the logical truths and the emotional constructs. I strive toward this goal and I'm glad to see that others do as well.
Woah, got pulpit-ty there, sorry.
