Most people’s writing would improve if they wrote more like they talked. You probably learned how to write in an academic setting and do most of your writing in a similarly formal setting. While you’ve probably had plenty of casual conversations in text, people often don’t consider that “real writing” and try not to let it affect their writing style. But you’ve got so much experience breaking things down and clearly conveying them in casual conversation that could benefit your writing with a small change of mindset.
