Awesome thread! N in my opinion would develop when you quieten E/I, F/T and P/J Just be... day dream, calm down totally, release all tension and anxiety and smile a bit that your privileged to be in your own company... and let it flow...dont analyse dont feel dont judge dont react. just let it flow in any direction or in no direction, just a mute observer.
i remember sitting in the classroom as a kid and just looking out at the clouds, observing them waft, sometimes shiny, sometimes white sometimes grey, from one end of the window to the other... and hearing the teacher teach and absorb just fine while still day dreaming. She complained to my parents but all they asked was, are his grades falling... quite to the contrary. and that was the end of it.! lol
