In order to even begin to learn how to play his instrument, it takes the guitarist weeks to build calluses on his fingertips; it takes the saxophonist months to strengthen his lip so that he might play his instrument for only a five-minute stretch; it can take the pianist years to develop dual hand and multiple finger coordination. Why do writers assume they can just “write” with no training whatsoever-and then expect, on their first attempt, to be published internationally? What makes them think they're so much inherently greater, need so much less training than any other artists?
