Would you say that this means you would be happiest keeping your poetry writing as a hobby rather than a full-time job?

Hell, yes. While I do actually have a separate passion I hope to someday make a vocation, and I get a great deal of pleasure out of problem-solving in work situations, I would never want to make a career out of any of the creative arts I dabble in. It would kill the joy, and I would feel insecure and unmotivated.
