To the artist, all problems of art appear uniquely personal. Well, that's understandable enough, given that not many other activities routinely call one's basic self-worth into question.

Uncertainty is the essential, inevitable and all-pervasive companion to your desire to make art

Art is a high calling - fears are coincidental. Coincidental, sneaky and disruptive, we might add, disguising themselves variously as laziness, resistance to deadlines, irritation with materials or surroundings, distraction over the achievements of others - indeed as anything that keeps you from giving your work your best shot. What separates artists from ex-artists is that those who challenge their fears, continue; those who don't, quit.

In the end it all comes down to this: you have a choice (or more accurately a rolling tangle of choices) between giving your work your best shot and risking that it will not make you happy, or not giving it your best shot - and thereby guaranteeing that it will not make you happy. It becomes a choice between certainty and uncertainty. And curiously, uncertainty is the comforting choice.

Tolerance for uncertainty is the prerequisite to succeeding.

Talent may get someone off the starting blocks faster, but without a sense of direction or a goal to strive for, it won't count for much

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.
