Always take it with a pinch of salt. I say that I only take my lessons and beliefs from experiences. The Myers-Briggs test had a lot to say about my person, but some of them were off. That was who I used to be. And you mentioned something about if these test are all that we are. Someone told me yesterday that he instinctively knew I was INFP but I moved contrary to the traits of my personality which was beautiful to him because I was working outside my comfort zone. I have done things outside my comfort zone this year and some I got hurt by but I still came out and did it all over again... hahaha.
