I came across a video today of Ira Glass, the host and creator of NPR’s "This American Life" discussing the art of storytelling, and think it is an outstanding primer on the effort it takes to produce excellent art, regardless of genre.
His bottom line–you have to produce large volumes of work–much of it not up to your own ‘taste’ standards–before the good stuff starts to manifest.
