I knew better than to point out the obvious: without red lights, we'd all be smudges on the road. Red lights are a tiny pause that brings order to life.
My last two books, I've gone through pretty major revisions with both--AFTER I thought I was done. I'm a speedy little writer, so I like to whip a manuscript out, revise it like mad, get myself worked up, type "THE END" and ship it off. Goodbye! I hate revisiting them afterward, and I hate even reading them again. It's worse than boring. It's agonizing. What if I see something I want to fix?
But both times, after months have passed, I've had to go back into the books with a fresh eye and look for opportunities for revision. And both times, I've been surprised how much better I can make the book with a little distance. So now I'm a believer in the literary red light. Finish your book. Then wait until the initial flush of emotion goes away. Then finish it again.
