Writers publishing for the first time often lack the understanding of the complete process. The number one virtue in this business is patience. Remember it took JK Rowling 10 years of patience before Harry Potter became successful. Overnight success is unrealistic.
So to illustrate this, I’m including this diagram from the Huffington Post.
If you are not Stephen King, Lady Gaga, or one of the Real Housewives, follow ALL the arrows. AND if your publisher doesn’t pull out his or her hair or become a goat farmer, you will publish your book–but NOT instantly.
