Fuck yes, you do, therefore you ARE. One of the questions that always astonishes me is “how do you become a writer?” You do it by writing! I knew I wanted to write for a living when I was a kid. Had my first work published professionally at 17, was writing for a living by 19, paid my way through university by writing. I’ve never had a ‘day job’ as anything other than a writer. You wouldn’t work as a rocket scientist if you wanted to become a farmer, the same principle applies. Looking forward to your book!
