Hello Sarah! I think your work can still be unique regardless of what the title is. The aim of my headlines is to attract readers first, and then the rest of my content is where the real creative magic can happen. The body of the article is where we should try and make our work unique, based on personal experiences, research and opinions - I see the headline as more functional, and a way to help the reader know instantly what they're getting into. Most readers will skim your headline amongst hundreds of other headlines - if your goal is to get more readers to your work then sometimes we have to forgo even the most beautiful, poetic and creative headlines, otherwise our articles may be skipped if they're aim is not immediately clear or if they come across as too abstract.
