From Art and Fear by David Bayles & Ted Orland

"Making art means working in the face of uncertainty; it means living with doubt & contradiction, doing something no one much cares whether you do, and for which there may be neither audience nor reward. Making the work you want to make means setting aside these doubts so that you may see clearly what you have done, and thereby see where to go next. Making the work you want to make means finding nourishment within the work itself."
