Most serious artists keep a sketchbook. While there may be some drawings in there, most of the drawings are not “art” but rather a record of a certain kind of mental exercise (namely deep observation of the world or visual thinking). We don’t call piano scales Music or sports drills Football, neither should we call learning to draw making Art. Many students get bogged down when they are learning to draw with how the drawing looks (not whether it is accurate or not, but rather whether or not they could proudly show it off).
“Results are best when they come from the right kind of unself-conscious effort… The time you spend (drawing) only counts if you are having the correct experience… “
