Just a Follow up

"Ask any writer or filmmaker or painter just how much of a given project truly represents what he/she envisioned it to be. You'll hear twenty percent...ten... five...few will claim more than thirty. The mastery of one's medium is the degree to which that percentage can be increased, the degree to which the artist's ideas survive the journey--or, for some artists, the degree to which the inevitable detours are made useful by the artist."
