I don't get inspired so much as, I wake up, and I do the work. Some days that work feels inspired. Some days that work feels like I'm pulling teeth from a rabid dog by going through its asshole.
The thing is, when I feel inspired, the work isn't necessarily better. Sometimes its worse. And on the days when writing is hard, when every word feels like I'm carving it out of my own hide -- the work isn't necessarily worse, either. Most times, months down the line, I can't tell by reading the work whether I was feeling inspired that day or not.
