I thought this was a nice way to sort of introduce myself...and I love quizzes like this. Although I have to agree with other posters, depending on the situation I was in I would tick yes or no, it would be different. And I wanted to agree with a different option based on how the question was worded. But my results were INFJ.
So Introverted, Intuitive, Feeling and Judging.
I agree about the first one definitely - I can only really communicate my true feelings and thoughts with those closest to me, and that's not a role they win easily! I am also known for shutting down even with them if the topic has gone a bit too far one way...though I'm better at that than I used to be. I love writing and that form of self expression, but also want to build systems...and sometimes I do get internally conflicted...I wondered if any other INFJs feel the same?
I especially liked question 21 - do you use every minute of your time productively? Well...I was filling in a long quiz when I should be considering an essay. So I answered yes, of course!
