A simple yet crucial concept, especially when it comes to poetry, is the position of the author and the speaker. I’ll provide a brief recap: the author is the person who wrote the work, the speaker is the narrator or who is telling the story to the audience. In poetry, I think of the dramatic monologue by John Donne My Last Duchess, in which the author is Donne and the speaker is a fictional character. You can find the poem here.
I won’t belabor a straightforward idea, but I want to draw attention to it to remind writers of the possibilities of perspective and that “We lose vast amounts of possibilities in writing when we only focus on ourselves as subjects” (quoted from a blog that goes into further detail).
