Inspiration - Where does it come from?

David Lynch talks about where ideas come from. He likens it to fishing. The intention to write a story is like dangling the bait in the water. Sooner or later a little fish - a tiny idea - comes along and takes a bite. You write down that little idea and it pulls in a bigger idea and so on. I like this analogy. Right now I'm wandering along the riverbank trying to decide on a good place to sling my hook.
Another place where we can find inspiration is in all the stories we've ever heard or read or seen in our lives - like this seven-year old writer creating a new version of The Boy Who Cried Wolf and making something unique and wonderful out of it.
