I don’t like to push forward with a story or novel unless it seems to me that the prose is strong enough to be permanent, even though I know very well that once the work is finished I will want to rewrite it. The pleasure is the rewriting. The first sentence can’t be written until the final sentence is written. This is a koan-like statement, and I don’t mean to sound needlessly obscure or mysterious, but it’s simply true. The completion of any work automatically necessitates its revisioning.
-Joyce Carol Oates
