lol, i feel the same way about Ti, it's my crappiest function by leaps and bounds. i have to admit, the deceiving role sounds pretty accurate.
Se, on the other hand, i really like. i'm not very good at noticing bundles of detail all at once, but i get sensory stuff in Fi pulses/impressions... i really love letting Ne "tune out" sometimes, and letting Se automatically tune in, like a passive thing - during yoga, driving (fast), biking, horseback riding, floating in the ocean, rollercoasters with lots of flips and turns, etc. ... it's calming and reenergizing to me. not to mention i kind of love the adrenaline rush when pushing it with the more physical things
i have a hard time thinking i'm really that psychologically advanced to have my last function going decently for me, but maybe i just got lucky to like things like very tactile arts (pottery, painting, drawing, etc.) and enjoying pushing the limits physically, both of which happen to involve Se. maybe the energy i use for Se ends up being taken away from poor Ti too O_o;
