There are a lot of things you can do to rev up your writing. Sometimes, the mental exhaustion takes over even when you are ready to write. Those moments mean that what you are working on is too on the front burner and your brain is melting down as a result.
The best method: Flash fiction.
Flash fiction is taking three components and making it into a story.
Take an object, a character, and a place.
Then, make a story out of it.
The story doesn’t have to be good. It shouldn’t always be something you want to save or keep forever. It is a way to push those ideas forward, get yourself in the mood for writing and return to those things that you want to write about.
News reporting in many ways uses the flash writing beast the best. A snap of the fingers, too many little stories, little components in order to develop your writing. Forget the bad sentences, the wrong paragraphs or terminal edits. This is about you developing a small story to push yourself back into the writing mode.
That object: apple.
That character: A fat worm.
A place: On the kitchen counter.
Now, think of the possibilities. A lot of them. Including a side character who walks in on the worm coming out of the apple on the kitchen counter and shrieks. Or maybe the person eats the worm out of indifference (extra protein). Or what if its from the view of the worm, who gets stuck in the apple and is screaming as the human comes forward with a knife (or drops the worm’s living remains in the trash compactor).
A lot of ideas just came to me in this. It builds a story quick. Maybe its funny, maybe not. But who cares. It gets me in that writing mood. And that’s what counts.
