There are two things that the essay writers I talked with suggested: more reading and more writing. Essay collections like the Best American series, that draw from a wide range of venues (whether literary journal, blog, or science magazine), can give a reader examples of structure, voice, and other craft elements. Finding a reason to do regular essay-writing — whether a personal blog or even a deadline with another writer — can move essays from vague ideas to words on the page.
Even when you’re not working on essays, ‘you can take the opportunity in almost any kind of nonfiction writing to amp up your own voice,’ Hopson says. ‘It doesn’t leave you, once you create a strong, personalized voice as a writer. It just winds up in things.’"
