I was just smiling over Holly Cupala's post on her
revision. Chatting with authors the past nineteen years, I find there are two approaches to writing a novel. I believe it became apparent to me when I was speaking with
Randy Powell.
The first is like Randy and Holly. They are like Michelangelo sculpting a large piece of marble.

They write many, many, many words (their blocks of stone) and then they begin to chisel. Tap, tap, tap. Until the story forms and stands before them.
Ah, a reason to post David. :~)

Then there are writers like me. We begin with the thinnest armature wire.

What different processes! And yet both end in novels! So, which are you?
