Only when you have completed a novel, or a story, can you return to the beginning and revise or rewrite.
I was working on the proof of one of my poems all the morning, and took out a comma. In the afternoon I put it back again.
I remember, the players have often mentioned it as an honour to Shakespeare, that in his writing (whatsoever he penned) he never plotted out a line. My answer hath been, would he had blotted a thousand.
By the time I am nearing the end of a story, the first part will have been reread and altered and corrected at least one hundred and fifty times. I am suspicious of both facility and speed. Good writing is essentially rewriting. I am positive of this.
If I revise a children's book, if I'm spending three hours on the first draft, I'm probably spending 30 minutes revising it. I mean, come on! But to redo a painting? That's hard work.
I am inclined to think that as I grow older I will come to be infatuated with the art of revision, and there may come a time when I will dread giving up a novel at all.
Somewhere I put it this way: first drafts are for learning what one’s fiction wants him to say. Revision works with that knowledge to enlarge and enhance an idea, to reform it. Revision is one of the exquisite pleasures of writing.
In a novel, you can always go back and make it look like you knew what you were doing all along before the thing goes out and gets published.
