I always seem to hit INFJ, or is it INTJ, or both...I can never remember. There was that very long personality type test which broke up things into five characteristics, which were themselves broken up into five characteristics, giving you a percentage score on each of the "you score higher on this characteristic than ##% of the population". I think that was posted here actually. I do know that, no matter my mood (which has the rare high, the normal sub-par middle of flatlined mediocrity, dullness and unreality, and then the ugly darkness), I score 99% introvert and 99% neurotic on that one.
I do enjoy these things though. I think, with consistency, they give a better degree of insight to yourself, not by way of excusing anything or giving up on any thing you are unhappy with, but helping you find the individual paths to resolving or alleviating simple or deeper problems, or similar with happiness or contentment, bot to mention how we interact with people.
Of course that "What Lord of the Rings character are you?" questionnaire that old me I'm Saruman and not the hobbit i wanted to be can just get a wizard's staff up it and go straight to Mordor, dammit.
Cheers,
