Nature places a simple constraint on those who leave the flock to go their own way: they get eaten. In society it's a bit more complicated. Nonetheless the admonition stands: avoiding the unknown has considerable survival value. Society, nature, and artmaking tend to produce guarded creatures.
David BaylesTo all viewers but yourself, what matters is the product: the finished artwork. To you, and you alone, what matters is the process: the experiences of shaping that artwork. The viewers' concerns are not your concerns (although it'd dangerously easy to adopt their attitudes.) Their job is wahtever it is: to be moved by art, to be entertained by it, to make a killing off it, whatever. Your job is to learn to work on your work.
David BaylesThe seed of your next artwork lies embedded in the imperfections of your current piece.
