Yet another great question! You guys are awesome.
Sometimes creativity comes in unusual ways. My inspirations usually come from What If questions. So for example, I might try to come up with a what if and then take that one and twist it somehow. A good exercise is to come up with something that doesn't have to be original, but then change one element of it. Keep going until you have a bunch of alternatives. For example, start with:
- Girl falls in love with werewolf.
- Boy falls in love with werewolf.
- Vampire falls in love with werewolf.
- Boy hates werewolf and is jealous of popularity.
Keep going until you have some crazy ones. Chances are there won't even be a werewolf when you're done. ;D
Another exercise I like is writing a scene in first person from a different character's POV.
