Everybody is different. Some writers can write reams of great books and then J. D. Salinger wrote just a few. Beethoven wrote nine symphonies. They were all phenomenal. Mozart wrote some 40 symphonies, and they were all phenomenal. That doesn't mean Beethoven was a lesser writer, it's just some guys are capable of more productivity, some guys take more time.
Billy JoelI'd rather laugh with the sinners than cry with the saints - the sinners are much more fun.
