Writing poetry can help you imagine the persona or personality you have. Then you can use that character in a story. Bradbury encouraged writing poetry or reading it in his book called zen. IMO the literary is highly linked to poetic techniques because of what he said. If you know how to write poetry you can make a good try at a literary short story. Reading it can also inspire. However, that is my opinion. What is your opinion concerning your knowledge about the topic? From symbolism, theme, alone I know it can make a difference.
