A poem is another way to express yourself through rich vocabulary and rhythms. Poems are based off of feelings, our environments, and our personal experiences. It is essential for a poem to have one main idea and a variety of similes or metaphors to support the main idea in a unique format. A poem should have a certain feeling or mood to it and it should in some way affect the reader emotionally. Patterns are also very important in a poem so that there is some sort of structure for the piece of writing. A poem is much deeper than other types of writing because poetry shows a writer's feeling in a special way that other forms of writing can't capture as well as poetry.
