If you are writing, you are an author whether you are published or not, whether anyone reads your work or not. A professional author doesn't need to write full time and usually has a day job. A professional strives to perfect every word, every sentence, every paragraph, every scene for a higher proficiency and skill. The writer's journey is life long. We write because we must, not because we want to see a paycheck.
As another author said at a convention, "There are far more easier and far less painful ways to make a living than writing." The true writer doesn't care and keeps cranking out pages.
I hire professional part-time staff who are full time students. They are amazing. The term professional writer isn't a designation granted only to full-time pursuits, but exemplifies the dedication to learn, to sweat, and to keep your butt in the chair in front of the key board.
I am a professional writer. I am not published, but I've taken this journey all my life. I've only been a professional for twelve years. My butt is in that chair every morning from six until eight--rain, shine, writer's conference, vacation, ill, whatever.
I wish you well on your journey. Think of it as a road trip up a mountain. You start in the foothills where you can't see or imagine the top. Once in awhile, you get a tantalizing glimpse of the roughed peaks. The vast majority of professional writers are in the foothills. If you are speaking of hiring an editor? I fear you might still be in the badlands and not yet to the foothills. Still, I wish you well on your journey, but spend your money wisely. Spending your disposable income on a maybe wish before cranking out not just a nice story, but a fantastic, incredible, can't put down work--and you've gone through countless, countless, and yet more countless revisions and drafts--do you spend your money wisely for an editor. I've heard that most authors have eight completed and perfected manuscripts before they get the next one published. Where are you on that scale?
I hope that isn't discouraging, but let's face it--becoming a writer also requires a tough skin. Best writing wishes and enjoy your journey. Celebrate each step and every accomplishment!
