Take a short poem, like a haiku or even a six word story/poem, and expand on it. Fit it into what you have been writing. Use one you haven’t written. Why? Because you need to imagine what the story is behind the piece. Imagine what was going on in the writer’s mind and run with it. How does that fit with what you are thinking with your writing.
Stretch the piece. Stretch your creativity.
Happy writing!
