Salman Rushdie was asked if the key to writing is inspiration. This was his answer:
It’s not inspiration. I think inspiration is nonsense, actually. Every so often, I mean like one day in 20 or something, you will have a day when the work seems to just flow out of you and you feel lucky. I mean you feel and often surprised and you don’t quite know why it is working like that. And on days like that it’s easy to believe in a kind of inspiration, but most of the time it’s not like that. Most of the time it’s… 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.
