I’ve talked to dozens of best-selling authors about their early years, before they were published. And the similarities between them are striking.
On average, they wrote about half a dozen unpublished manuscripts before they sold a novel. (By the way, this is what I call the Myth of the First Novel. Because it’s hardly ever the first novel they wrote. Just the first one to get published.)

They read every day.
If you want to get published, you need to be an avid reader. Here’s what you should read.
