You don’t have to Draw “Something.”
Something will come to you.
You don’t even have to possess a “Photographic Mind Map” like Kim Jung Gi (whom I do not consider to be “My” Master).
You do not have to know of, or fully understand perspective; nor all of the other “Skills” that you believe are necessary for Drawing.
You simply need: a Pen, a Piece of Paper, and a Simple Line.
Once you make the first mark on the paper, let it take you on a ride. Do not attempt to control it, just go with the movement of your hands and the changing patterns of your mind. Let the past become the future, and the future made void. Take in the Universe and expel expectations out.
Voilà; you will eventually create “Something.”
