Poems can't be forced. They come when they want to come. I have found though that they can be elicited by prompts. One or two of my better efforts have come about because someone gave me a topic to deal with- and sometimes a topic I'd never have tackled otherwise.
T.S. Eliot said there was no such thing as a poet, there are only people who write poetry. I think that's right. Poetry comes and goes. Just because you wrote poetry in your youth doesn't mean you'll go on writing it all your life. Eliot himself is a good example of a writer whose gift deserted him. He wrote great poems from youth through middle-age but the love poems he wrote for his wife in old age are embarrassing- and he must have known it because he held them back from publication. Most Collected Works contain a good deal of filler. To set yourself up as a poet and commit to turning out slim volumes on a regular basis is to ask for trouble.
