That isn't to say you shouldn't slave over a poem. There are a few that I have, and I always feel unhappy with those. I've come to feel that no poem is ever truly complete without a reader, and the poem actually completes itself within the reader. Most of my poems can have multiple interpretations and are left open-ended quite intentionally.
Poetry is a way for me to share ideas and concepts that I feel mere prose do not properly capture. This necessarily means that I often abandon rhyme scheme, but not always. I tend to use stanzas, but not always. There isn't one poem I can really look at and say: “That's definitely my poem.” I purposely do not have a favorite way to write poetry. It is just what it is for me.
The reason that I use the idea of “from the pages of spiral notebooks” as the overarching “theme” of my poetry is that in many cases, that's where most of my poetic work has come from. Some of my poems came from scrawls in the notes of various classes over the years. Many literally came from spiral notebooks dedicated to stream of consciousness and journal writing. Yes, even now as many are input into a phone or typed on a computer in their initial form still have that free spirit to them.
The idea of poetry for me is that each individual piece has its own voice, its own purpose, and its own personality. They are blossoms, each with its own DNA and individual spirit. Over the years, I've pruned the garden for poems that lacked flow or essential purpose, but the misfits are usually left alone. The variety is what I appreciate most about my own work. I want it to stay random and spontaneous. If I work too hard on one poem, what it does say for my others?
These are just thoughts on my own poetry. When it comes to others' poetry, my viewpoint is rather different. I fully appreciate the blood, sweat, and tears that go into many poems, how carefully many words are chose, how the rhythms and meter are so carefully crafted. Once I tried to do that with writing lyrics, and sometimes a lyric still comes along, but I no longer expect them.
Poetry is whatever it is to you, but more importantly, a poem is at its best when it completes itself in the reader's mind. That's what poetry is for me.
