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.
