Hello. I'm Amanda, and according to a couple of online tests, I'm an ISTP - as far as working it out for myself, though, it really depends on my mood as to whether I agree with the ISTP verdict. It superficially fits, but ISTP seems too ... eh, reckless? I'm really a scaredy-cat. I don't even like driving at night-time because I'm scared of super-intelligent zombies attacking me in my car. :\
Enfin, as far as enneagram numbers are concerned, I have less of an idea of myself than I do with regards to MBTI - at least I'll come out and say 'hey, I'm probably an ISTP'. I can't find any types that I agree with, and when I begin to take wings into account, it all makes less sense. Depending on the day, I swing between 2, 5 and 8. It seems pointless - my motivations are too malleable/diverse for it.
