Your title should actually read: “If you want to make money as a writer…”
I am a writer. It’s what I do. It’s what I’ve done for years. And I blog. No copy writing here ever.
Plus, I don’t even agree that you can’t make money as a blogger. I do. I make a living solely by blogging.
Besides which, I have no freaking interest in writing copy for other people. As a writer, I want to showcase my work period.
