about writing process

I've written a lot of short stories and a number of novels and I've done them all the same way. I start at the beginning and write through to the end and then I realize that the ending completely changes everything. So I go back to the beginning and revise everything and get to the end and realize it changes everything and so on. With my first novel I did that about 40 times. Literally.

Since then I've become a little more efficient, but I've always liked the idea of hurling myself forward...
