Could be a painting, a story, a movie, woodworking, absolutely anything. Also why?
If youβve had poems published without really understanding poetry itself, you may naturally have an intuitive grasp on poetry. I think it would be interesting if you continued writing and reflect on what you write, how you write it, and how you feel while writing it. Maybe write a poem expressing your feelings on poetry!
Then again, studying could give you better means and terminology to express your internal understanding. Either way, I wish you well!
