For many years, I did what everyone had to do if they wanted to be published. I plotted and started writing the book, and as I got towards writing THE END (metaphorically speaking - I never actually DID write that!) I starting thinking about how I was going to sell it.
It was a daunting prospect. Everybody knew that only a small fraction of books submitted ever got published. Worse, we'd all heard about authors who got positive feedback and "try us again" letters, but hadn't made it past the finish line because of bad luck (another book too similar just accepted, or rejected by a close vote in an editorial meeting).
Write, query, query, query, query, query... some people had their a book rejected by upwards of thirty publishers before they gave up and consigned it to their own little 'rejects' pile. Sometimes they'd start all over again, sometimes they gave up.
Now, with Indie publishing, the publishing scene has changed so dramatically that authors have to make entirely different decisions, related to taking the reins of their own publishing business. (For it is a business: you are the writer and the publisher.)
Hugh Howey has written a thought-provoking post, Renting Vs. Owning, that pretty much lays out what many of us have been thinking for a long time. Read it, and see what you think.
And while you're there... also take a look at the clever one-line tags for each of his books. What could you write for each of yours?
