Creative people are especially observant, and they value accurate observation (telling themselves the truth) more than other people do.  They often express part truths, but this they do vividly, the part they express is the generally unrecognized; by displacement of accent and apparent disproportion in statement they seem to point to the usually unobserved. . . They have more contact than most people do with the life of the unconscious -- with fantasy, with reverie, the world of imagination.

Art, true art, depends on what the artist emphasizes and what the artist ignores. It is a search for something deeper than the surface facts or appearance. It is a search for the essence of the thing.
