According to Dr. Friedman a well known pyshcologist, who authored a book called touched by fire, in her research she claims that Artists tend to have a physical difference in the structures of their brain, wich causes them to be, well lets just say more moody. Because they have differeing structures within the brain according to her research the artist litterally thinks differently than most people in other "professions" do. The end result being the "artistic eccentricities" often attributed to almost all of the great well known artists. Just some food for thought.
