I am very much an ENTJ, with 3 tests supporting that over the span of my life, along with those behavioral characteristics most often seen in individuals diagnosed with this dreaded disease - um, I mean, personality type. I say that because I live the challenging life of a female ENTJ.
I'll be slow to start in conversation, I am rather vigilent in any cyber environment, so it hinders aspects of my real personality.
It should be only a matter of time, though, before I jump in, spout off, and find that there is some remarkable INTJ close by, either to correct me or to shed perspective that I have not considered. BTW, I am delighted when that happens, because I enjoy friendly sparring, and I love learning.
