I've thought of this question often. Pondered it while I dragged a pen across the page or madly tapped words onto the wordprocessing doc. I haven't came up with a clear answer.
The one thing that I've realize that I really like about a poem, is being able to connect with the piece. Something that draws me in. Something that let's me have a moment to be beyond myself. To see things in a different light.
I think that this question is so subjective that everyone has different ideas of what constitutes as "good" poetry. It may feel daunting to share these pieces with others. My suggestion for OctPoWriMo-
Don't worry about making "good" or "bad" poetry. Just write it. Don't have any expectations of what you're writing. It's a series of rough drafts. You may go back to some of it later. You may find pieces that you love..and other things that you don't like as much.
It's all fine. An exercise like this is to get your blood pumping. Your poetry brain going. In a month like this, every poem you finish is a good one, because you did it.
