You make good work by (among other things) making lots of work that isn't very good, and gradually weeding out the parts that aren't good, the parts that aren't yours. It's called feedback, and it's the most direct route to learning about your own vision. It's also called doing your work. After all, someone has to do your work, and you're the closest person around.
David BaylesMaking art now means working in the face of uncertainty; it means living with doubt and contradiction, doing something no one much cares whether you do, and for which there may be neither an 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.
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 lessons you are meant to learn are in your work. To see them, you need only look at the work clearly - without judgment, without need or fear, without wishes or hopes. Without emotional expectations. Ask your work what it needs, not what you need. Then set aside your fears and listen, the way a good parent listens to a child
