I used to be obsesssed with MBTI. I dont trust a lot of the tests because most of them go by dichotimies as opposed to the actual function (ESFJ and INTP have more in common function-wise than INTP and INTJ, but you wouldn't know that from how most free online tests explain the results).
That being said, I'm an ISTP. Ti-Se-Ni-Fe.
