I enjoy randomness, which probably leans toward spontaneity.
After reading ptgatsby's responses, I'm thinking I'm naturally ENFP, but I was trained to be ENTJ. My father is an ESTJ and my personality strongly emulated his when I was younger. Though I've never been an S (I retreated into my mind a lot when I was a child), I did learn most of his other traits. It wasn't until I went to college that my natural personality started to assert itself. I still have remnants of that ENTJ personality that are available to me when I want them and they're certainly useful at times.
I'm actually thinking I may naturally be an ENTP (mainly because of my Socionics type, where I reportedly resemble an ENTp). I was just overprotected as a child and so may just think I'm an INTJ. Regardless, I retreated into my mind when I was young, as well.
I'm guessing you haven't seen my posts on INTPc, so that probably adds to your confusion regarding me. I think type is situational and I think the F/T distinction is very ambiguous and situational as well.
This sounds like something a P would say.

FWIW, Uber, I always come out INTP on that one. I am so not an INTP.
No, I was more referring to Socionics as the sort of Jungian phrenology -- reading faces to determine type. It's the way people's eyes look, and [a fellow member] PMed me and said I looked more like an ENTp.
And yes, I also normally come out as INTp on the Socionics test -- and remember that the Socionics INTp is the MBTI/Keirsey INTJ.
EDIT: In Socionics, INTj has a softer gaze, where the ENTp and ENFp have a more piercing "zeroing in" gaze. INTp has a more nervous look.
