One is born an artist. The artist is a man endowed with a special nature, with a particular feeling for seeing form and color spontaneously, as a whole, in perfect harmony. If one lacks that feeling, one is not an artist and will never become an artist; and it is a waste of time to entertain the possibility. This craft is acquired through study, observation, and practice; it can improve by ceaseless work. But the instinct for art is innate. First, one has to love nature with all one's heart and soul, and be able to study and admire it for hours on end. Everything is in nature. A plant, a leaf, a blade of grass should be the subjects of infinite and fruitful meditations; for the artist, a cloud floating in the sky has form, and the form affords him joy, helps him think.
