Minor rant: <grabs nearest soapbox and pulls weary body onto it.>
Writers as a whole want one thing: to write. But the REASONS why they write are as varied as the stars in the sky. Mostly, they can be broken down into three categories, ALL OF WHICH HAVE EQUAL MERIT!
1. Those Who Write for Money. The group of writers who write solely for the purpose of putting food on the table are a special breed. For this writer, chasing from publisher to publisher for the highest paycheck is the goal. In order to keep the paychecks rising, they must appeal to the majority of readers in the world. Sales to public = value of author. Lack of remainders = value of author. Advance sales of next book = value of author. If an author gets a $5,000 per book advance this year, then that number had better be $8,000-10,000 next year, and so on. Thus, in order to keep the advances increasing, the author must constantly improve their skill, always look to the market for the next hot trend, work furiously to pump out book after book, lest the public forget their name. If the readers are buying paranormal, the author writes paranormal. If two years later, the readers want historical, then by golly -- historicals will start getting pumped out. EVERY story can be made exceptional. EVERY genre has merit. What the reader wants, the reader gets.
2. Those who write for art. The artist doesn't care if their books get a million readers, or if there are any paychecks. The goal is to move their readers --- to laughter, to tears, to rage and fury. All of these emotions can be had through the skill of the author. There is a warm sensation; a satisfaction in knowing your words created something real and powerful inside a person.
3. Those who write for themselves. Some writers have voices in their head -- powerful voices that cannot be stilled unless they pick up a trembling hand and write words on paper. These writers don't care whether ANYBODY ever reads their work. It can sit in a desk drawer for all of eternity and is just as real and powerful and moving without a single soul ever laying eyes on it. It's a tree in the forest that will exist, whether or not anyone ever admires it. It's quite possible that this writer will NEVER show their work to anyone -- not because it isn't good, but because it doesn't MATTER. This writer needs no validation of their skill, no soothing of their ego. They write because they can't NOT write.
The thing that so many writers forget as they step into a bookstore and see tables upon tables of displayed books is that there's no requisite to be one of them!
Despite what this instructor said, regardless of what the craft books say, no matter what every interview on every writing website and magazine says, there's only one truth in writing:
IT'S OKAY NOT TO WRITE FOR MONEY!
Now, I'm a #1 style writer. I DO write for money. There's nothing wrong with it, and I always presume that when people ask about writing, that they're asking about HOW to write for money. So, that's the response I give.
But even if I was a #2 or #3 writer, I'm a perfectionist. I would still be required, by my own internal drive, to become the best writer I could be. Just as I took the time to take classes in embroidery, and others take classes in pottery, or painting or soccer. There's no "goofing off" in toiling to improve your skills.
No goal of publication required. The instructor was wrong.
