When I first started writing I didn't know there was such a thing as a writing well. I wrote happily when I wanted to. Didn't write when I didn't want to. I fluttered around all cutsie-like calling things muses and inspiration. If I could go back in time I would take a rolled up newspaper and hit me on the nose, "Sit down and write, you fluff for brains."
Now I know like that saying goes if you work hard, you've got to play hard. No excuses. No feeling guilty for taking care of yourself when there's still something on the to-do list. Life feeds into craft and craft feeds into life. I've got to live it. I've got to play. Then I can be serious about writing.
