If you’re reading this blog, chances are you have been told at some point, by someone, likely more than once, that you are a good writer. Maybe even a great writer. Your mom, maybe, as she pinned your block-lettered picture-sentence stories to the refrigerator when you were in first grade. Or the seventh-grade teacher who read your poem to the whole class, which was embarrassing but also super validating. Maybe you won a high school essay contest. Or your colleagues praise your memos and emails, perhaps, for their clarity or wit.

And you know it to be true. You have a knack for it. You’re comfortable with your fingers flying over the keyboard. It pleases you to put together a sentence whose rhythm feels right. Your mind bristles with ideas, clamoring to be let out onto the page.

But becoming a Real Writer? About this you’re not as certain.
