There are some good quotes in the Writer's Almanac piece. Here are two of my favorites (italics are mine):
What struck me is the planning part. As I mentioned in last week's post on writing, I outlined my entire first book before I started writing. And, even though I manipulated certain segments along the way, I still mapped everything before I wrote those new segments. I wrote the book in less than ten months. As of tomorrow, I will have officially spent two years NOT writing my second book. Thus, I'm going back to that which I know: outlining. I'll save the experimentation for book three or later.
She planned out the entire Harry Potter series before she wrote the first book, and she says: "I wrote the story I meant to write. If I lost readers along the way, so be it, but I still told my story. The one I wanted. Without permitting it to sound too corny, that's what I owe to my characters. That we won't be deflected, either by adoration or by criticism."
And she says, "You have to resign yourself to wasting lots of trees before you write anything really good."
