Examples of genius only accentuate that truth. The point here is that whatever his initial gift, Mozart was also an artist who learned to work on his work, and thereby improved. In that respect he shares common ground with the rest of us. They commit themselves to the work of their heart, and act upon that commitment. What you end up caring about is what you do, not whether the doing came hard or easy.

The ceramics teacher announced on opening day that he was dividing the class into two groups. All those on the left side of the studio, he said, would be graded solely on the quantity of work they produced, all those on the right solely on its quality. If you think good work is somehow synonymous with perfect work, you are headed for big trouble. Because you're a human being, and only human beings, warts and all, make art. Without warts it is not clear what you would be, but clearly you wouldn't be one of us.
