All creativity is cyclical and sometimes we aren’t as creative as other times. Whether you’re a novelist, a sculptor, a painter, or a hobbyist, some time periods you are more prolific than others. Writers sometimes refer to the uncreative time as writer’s block. Some people think writers’ block is a fatal disease.
I don’t think it’s even a setback. It’s a chance to breathe, learn, and get better at word craft. When your flow of words slows down, stop. Don’t force yourself. Writing is a craft. While I believe you have to work at it, practice, to become more accomplished, I don’t think writing should be forced. The best words flow freely and naturally. So just stop. And listen. Go to You Tube and listen to some great American orators speaking about anything. You don’t even have to understand the subject. Just listen to the flow of the words. Listen to poetry. I’m not a poet, but when I listen to poetry my prose is more fluent. Go for a walk and sing great lyrics for a song you’ll never write. These are all ways to get the words flowing again. You can call it writers’ block if you want. I call it opportunity to get better at whatever it is you write or craft.
