So, think of a story. Write it up in a poem. And in the process, make a discovery, come to an insight by poem’s close. You will likely have no idea what that will be until you start writing your narrative and you will see, you may very well surprise yourself in what you discover ! (My suggestion for your stories: think of something that has always troubled you, something that your mind keeps coming back to, maybe in dreams? maybe words stuck in your head? something that haunts you. That’s the psyche’s clue that the mind is trying to work something out, so give it this chance.
