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.

Making 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.

The seed of your next artwork lies embedded in the imperfections of your current piece.

Tolerance for uncertainty is the prerequisite to succeeding.

Even talent is rarely distinguishable, over the long run, from perseverance and lots of hard work.

To 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.

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.
