While I’d rather see a reminder that we need to know the rules of formal writing, so that we can choose to ignore them deliberately, otherwise this author makes a good case for the value of poetry. (Great training for the art of writing engaging headlines and story leads.) (See also “Poetry Writing Tips.”)

Poetry is not bound by the constraints of sentence and paragraph structure, context, or even grammar. In the magical world of poetry, you can throw all the rules out the window and create a piece of art, something that is entirely unique.

That doesn’t mean writing poetry is creatively easy. It can be much more difficult to make a poem than it is to write an essay or piece of fiction. There’s so much creative space, and without any limitations whatsoever, it can be overwhelming.
