KTC, I felt that same kind of shift you're talking about a few months ago. I never took my poetry seriously, or respected it, if that's a better way to put it, until this shift happened. I have a friend who used to call me on the phone and say, for instance, "Hey, there's a girl here in my office, a friend, who's getting married. Can you write me something special for her?" And I would say, "sure, call me back in an hour." I could whip off a pretty decent poem.
But when that shift happened, I became to flirt with the idea of writing only poetry. My attention span is short, so I don't want to write any more novels, maybe not even more short fiction. I want to dedicate the rest of my writing life to poetry, and hopefully make even half a name for myself someday, get some books of poetry published.
It's very exciting, this new direction I've taken. Reading, learning about, and writing poetry are bringing me peace, joy and hope for my writing future. It's exhilirating.
So, yeah, whipping off a poem for fun, there's nothing wrong with that, but when you start thinking about publication, this is when the game REALLY gets interesting and exciting.
Good luck.
