I see rhyming as not being that much of a "need" in Poetry. I've read many that did not rhyme and they were divine.
I see Poetry as needing "natural-flow" rather than rhymes.
To me as a writer, and for me as a reader...I look for the natural act of downloading ones feelings, thoughts, sights, etc., rather than looking to make sure the words rhyme. But then again I do not support the grammer police either, so its your call, that was just my crow/reply.
To sum it up; I look at Poetry as the most natural and substance free process of writing. You can write of anything, on any grounds and as long as it is "natural" it can be percieved well.
Quite a while ago I asked myself two questions; Why do I write? And....How do I write?
I write because I have to. These words start forming on my soul and I release them. I also write as a means of sorting my thoughts, as well as a release.
The how is the odd part. I am very much so a natural writer. In saying that, I mean that I do not sit over a keyboard and think. Most of my Poetry writings are done in 5-10 minutes. I feel as if I'm just a tool in the process, just a funnel. I sit and the words rip through me and into my finger tips to be typed. Its that simple, and that natural.
If I were to worry about outside forces, one being rhyming; it would take away from my reason for writing and my method of writing. Different things work for different people. Perhaps you should ask yourself the two questions that I asked myself and go from there.
