A simple pencil drawing can be so satisfying. Slowly and carefully drawing, focusing on the area just below the pencil, observing every detail of the subject. I try to draw every day. Mihaly Csikszentmihalyi, a Hungarian-American psychologist is the architect of the notion of  FLOW, which is “being completely involved in an activity for its own sake. The ego falls away. Time flies. Every action, movement and thought follows inevitably from the previous one. Your whole being is involved, and you’re using your skills to the utmost.” And an old Chinese saying, quoted by David Hockney, says: “Drawing needs three things, the heart, the hand and the eye, two won’t do.”
