This is what I came up with when I took the Meyers-Briggs in college.  Nik and I took another version of this test for our marriage conference last weekend and that one said I was an ENFJ.  I think it was a little off!  At the conference, they gave us extensive descriptions of the different types and I think ESTJ fits me a little bit better than ISTJ.  I’m definitely more in the middle on the E/I dimension than this test shows.
