I don't want to be evasive again, but I think that every act of writing presents a problem, whether it's in the first stanza or the middle or the end, suddenly there is a problem. The poem won't go the way you want it to go. You're not sure how you can possibly bring this to a resolution. Resolving that problem is very much a part of the writing. Writing poetry is not about self-expression, not so much therapeutic release of feelings. It's usually solving a problem and that problem is a verbal problem. Every poem presented a problem at some point that I had to figure out.
