No matter what you write - poetry or prose, fiction or nonfiction - voice, imagery and figurative language are essential ingredients for success. They are just as important when describing a current event as they are creating a fantasy world.
In order to hone my abilities in V, I and FL, I keep a notebook of words, descriptions and phrases that ring true that other writers have created. One that I fell in love with at the poetry reading was created by Amy D'Amico. The leaves "typed" across the pavement. Instantly I heard that dry clatter sound. Another phrase I liked was written by Nathaniel R. Fuller in his short story, Aster -- the man had "more warts than prayers God actually listened to." Who can't picture that guy? And you also hear the narrator's voice, jaded and world-weary. A two-fer. Excellent.
What words have captured your imagination? Keep a notebook and open your ears. Listen to the wonderful voices that surround you. It will make you a better writer regardless of what you write -- fiction or non-.
