Really, I should phrase that "letting the well fill." Part of the process is the letting, not the controlling, or worse, the forcing.
I've decided that letting the well fill isn't all about getting a new book idea. Because I have one of those. Sometimes it's about just shifting gears. Taking a vacation of the mind or spirit. Sometimes it's about being something besides a writer. Laying it all down -- which is quite distinct from kicking it to the curb.
Sometimes letting the well fill involves reading. Who am I kidding: centers on reading. But I'm going to be selective and persnickety about that rather than going on a binge or a feast. If I were a runner, I'd run, but since this is me, I'll walk. And contemplate, and...and nothing, because this is letting the well fill. And it's trying on for size the idea of needing to be nothing except God's daughter.
