Two quotes that may shed some light, but maybe not, I dunno:
Ezra Pound: "Make it new!" (boy that's hard)
Gary Winogrand: "We know too much about how pictures look and should look. And how do you get around making those pictures again and again?" (that quote is pinned onto the door of my camera storage cupboard, just to irk me when I'm about to pack to try to find out)
No more difficult questions, please.
