Creative people get bored. White pages repel them. Silence is a vacuum. See a brick wall, get a spray can. Now technology has created an infinite amount of empty spaces. We could make films and books and music and drawings and photos (god all these photos!) forever and not even scratch the limitless amount of blankness out there waiting to be filled.
I'll hit the post button. And immediately be greeted by another white page. It's enough to drive a person crazy.
