The first and only time I took the official MBTI was in college, and I scored INTJ. However, I think that was because I perceived myself as a Te type--structured, organized, and informed by authoritative sources--in response to the demands of my academic environment. Once I was out of school and living on my own, my true nature asserted itself, and I scored INTP on every online test. Interestingly, since I entered my thirties, those same tests now peg me as INFP or INFJ, but I think they've become useless for me because my Fe has developed to the point that it's skewing the results. After reading extensively about the functions, I knew I was Ti-Ne-Si-Fe.
