@sotolf With all this in mind, in my particular case I have been testing consistently N my whole life and the fact that I'm now testing S rhymes with my ambition to mature and become more well-rounded and open to other perspectives than my own, moving this trait toward the center.
Maybe it's self-fulfilling, maybe I'm answering as the person I'd like to be, but I'd find that interesting too, that my ideal would be moving toward my meta-ideal, my "ideal of an ideal", my intellectual idea of what I'd like my intuitive, emotional ideal to be.
