I agree with much of the INFJ profile, and also with much of the ISTP. Theres stuff in both that I dont think I match. I tried to narrow it down to one but I believe that I am different people in different situations/times, so not sure how to answer many of the questions. There have been times when I am very concerned with others, as well as times when I am a lot more aware of myself. How can I know which personality type best suits me?
