Get your facts straight. It doesn’t matter if you’re writing your own story or someone else’s. If readers, publishers, and the media find out you’ve taken liberty with the truth of what happened, you and your work will be ridiculed and scrutinized. You’ll lose credibility.
Issue a disclaimer. Most nonfiction is written from memory, and we all know that human memory is deeply flawed. If you aren’t sure about the details but are determined to include them, be upfront and plan on issuing a disclaimer that clarifies the creative liberties you’ve taken.
Consider the repercussions. If you’re writing about other people (even if they are secondary figures), you might want to check with them before you publish your nonfiction.
Be objective. You don’t need to be overly objective if you’re telling your own, personal story. However, nobody wants to read a highly biased biography. Book reviews for biographies are packed with heavy criticism for authors who didn’t fact-check or provide references and for those who leave out important information or pick and choose which details to include to make the subject look good or bad.
Pay attention to language. You’re not writing a textbook, so make full use of language, literary devices, and storytelling techniques.
Know your audience. Creative nonfiction sells, but you must have an interested audience. A memoir about an ordinary person’s first year of college isn’t especially interesting. Who’s going to read it? However, a memoir about someone with a learning disability navigating the first year of college is quite compelling, and there’s an identifiable audience for it. When writing creative nonfiction, a clearly defined audience is essential.
