When it comes to the poetry I write, I am a slave to my form. It's all rhyme and rhythm, and I feel in a way that the writing should be measured by the meaning one can drive into a skeleton of a poem. This isn't to say that I have a form in mind when I start writing, but as I write I find it; for instance a rhyme scheme and number of syllables per line. Even my streams-of-consciousness and free-verse-type-poems follow this pattern, and the only irregular poems I've written are ones that I really enjoy but were written very angrily and not easily recreated.
This being said, I am starting to think that my poems are too similar to one another, at least in form if not in topic, and although I like them I would like to improve. So could improvement happen by trying to remove or pay less attention to some of the form? I guess we will see.
