Keep Writing, as You Market Your Book(s).
You can’t afford to forget daily creation, because you’re focused on promotion. Creation is vital if you’re writing books.
In days gone by, months and years could pass before you got an agent and publisher. If you did manage to interest either one, they wanted to see “WHAT ELSE YOU’VE GOT”. They wanted to make sure that you were set up for the long haul – why waste money on a one-book wonder? Books from new authors lose money.
