I don't even understand that question. Before I could read and write I drew my stories in sequential panels. As soon as I could write well enough to write a story I did. I've written something almost every day of my life since I could hold a pencil. It's everything else that I need to be inspired to do. Writing is my resting state. If you're a fiction writer at your core, you're automatically filing away everything you see as a reference for a future story, you're running character dialog in your head or out loud in the shower, you're scribbling ideas over soy sauce smudges on a napkin at your anniversary dinner--it's just what you are. Now, the discipline to see things through is another matter, but it's not inspiration. It's grit and determination. It's a conscious decision to do the hard part of being what you are instead of letting life give you excuses to be something else and die without ever realizing the purpose of your soul.
