1. Music: When I get stuck in a scene, I find playing music can jog my brain. Maybe it's because music appeals on an emotional level?
2. Rain: I find that I get inspired by the rain, and I find it easier to get write on cold, damp days. Good thing I live in Ireland then.
3: Reading history and mythology: I find that my YA fiction depends more on my university education than my adult fiction does. The political situation in Ravensborough is inspired by historical research, and my steampunk WIP is based in an alternative Victorian era, a period I've specialised in. So non-fiction comes into play.
4: Eavesdropping: It's amazing how many ideas you can pick up from listening to people talk in public. Not that I would lift an idea completely, but if gives you a starting point. Then you ask 'what if...' and a plot strand begins to take shape.
5: Life: This sounds like a bit of a cop out, but it really isn't. The more things you do, people you meet, and places you see, the more your imagination grows. Like any living thing, creativity needs fuel.
