“What should I write?”
Writers tend to ask this question. A lot. The short answer of course, is anything you like. If you’re writing professionally — that is, if your writing is your entire income, or a good portion of it — you need to go with your instincts.
Sometimes this is translated to: “make money writing about your passions.” This is fine, as long as your passions are profitable. For example, if you’re a keen runner, chances are you can make money writing about fitness and health.
Or perhaps you’re passionate about your family. Many bloggers make a great income writing about their parenting challenges, and everything that goes into running a home.
