So I've always had a passion for writing ever since High school, why I never actually pursued it, I am not sure. 15 years of Over-the-road trucking just came to a screeching halt due to medical reasons and basically, I need a work-from-home type job to make ends meet. Freelance writing is a great fit, the only problem is my resume only shows trucking and some old IT work back in high school. The only real thing I have to show for myself is that I self-published a Novel in 2019 and just finished writing its sequel, but it's not out in the world yet.

How do I develop a resume and/or portfolio to show off my nonexistent work for writing as a 38-year-old who is pursuing work-from-home clients/jobs/work when the last 20 years of my life were trucking / IT?
