If you’ve ceased to ask why sand is the color of sand, why the sky is blue, or gray, or why the sea doesn’t have its own color, then take a look, and think about it. The purpose of art is the purpose of life. Your past is a museum. The purpose of your present is to use your eyes and brain; to see each moment as a new canvas. If you’ve ceased to ask why painters paint, why musicians compose, or poets write poems, you can start asking and let each moment answer.
