WHEN YOU’RE TRYING TO BE a writer for hire, you agree to writing pretty much anything people will hire you to write. Sometimes that means agreeing to write for a celebrity dentist/beautician when you’re a disgusting bearded guy with no healthcare. Sometimes that means convincing Nobel laureates to attend a global forum on a topic you got a 1 on for your high school AP exam.
My point is, if you’re not an expert in something, you learn how to sound like one if you want to get paid, and by proxy you figure out how to sound like the people who actually are the experts. And through it all, you learn some valuable things about people, as I have.
