Salman Rushdie says "Inspiration is nonsense!"
"I mean, I wish there were more of those days, but most of the time it’s a lot slower and more exploratory, and it’s more a process of discovering what you have to do than just simply have it arrive like a flame over your head. So I do think it’s to do with concentration, not inspiration. It’s to do with paying attention, and I think the business of writing, a great deal of it, is the business of paying attention to your characters, to the world they live in, to the story you have to tell, but just a kind of deep attention; and out of that if you pay attention properly the story will tell you what it needs."
Sounds like he's with Thomas Edison (another Ohioan, by the way)... it's one percent inspiration, and ninety-nine percent perspiration.
