I try to show what it is about language and music that enthralls, because I think those are the two elements of poetry.
Instead of trying to come up and pontificate on what literature is, you need to talk with children, to teachers, and make sure they get poetry in the curriculum early.
Crassly put: When I write, I am trying not to bore myself and my readers.
At the very beginning when I begin writing a poem I try not to think of the audience or anyone at all except for trying to get at the very center of what is driving that poem. In a way it's like analyzing myself.
If I begin writing a poem that means I'm intrigued in some way by whatever it's about and that if I'm not trying to find something new and pushing the envelope in the poem I can't expect my reader to be particularly excited about it either.
