There is no doubt that poetry is a medium for feeling but if it were that simple the stuff you would see on the inside of the door on a public booth in a men's or women's public lavatory would qualify as poetry. Not to say that some of that stuff is not poetry but the bulk of it is simple emotion without skill. Good poetry requires skill with language, with the various tools of poetry, with deep understanding of people, history, current understanding of the many aspects of the world. We all have lacks in these huge areas but we do the best we can. Even with all these considerations, many experienced poets fail. There is a special magic in choosing the right word, the right metaphor, the right way of assembling all these various skills to get a poem that surprises even the author. I do not say this to discourage anybody, merely point out something worthwhile is not necessarily easy. But, occasionally, surprisingly, it is.
