Authors are just ordinary people. Really?

​I heard Liane Moriarty (author of, amongst many others, the soon to be filmed Big Little Lies) interviewed this week and she talked of the realisation she had as a young girl that authors are just ordinary people and I ask myself - could I possibly become one of those just ordinary published author people? Of course there are authors that were never just ordinary. Virginia Woolf was born a genius and James Joyce an aberration of humankind but if we bring it down a notch to authors who lots of peoples still love reading (sorry Virginia and James but its true!) I guess the Kates -  Grenville, Forsyth and Morton were just ordinary person once. They cooked and cleaned and procrastinated writing blogs (well maybe not the last one!) Not that I'm comparing my writing with any of these giants but you get my point.
Anyway back to reality. My journey towards publication continues. With no take up from any agents yet I have relooked at the opening of my synopsis with a greater focus on the mystery of the music and I’m even considering revamping the novel’s title from The Unknown Concerto to Vivaldi’s Lost Concerto to better capture attention. What do you think? I’ve also applied to enrol in a Pitch Conference with SA Writers and was lucky enough to score a late backfill into Fiona McIntosh’s September Masterclass. At both of these events I’ll come face to face with some real life publishers. Very Exciting Times but with that comes the realisation that I can’t hide behind the “I only write for a hobby” cover or use the “I only write part time” excuse. This is real author business for a just an ordinary person.   
Wish me luck and let me know in the Comments if you have any thoughts on the just ordinary people notion.
