So here are your action items:
If you don’t have an author website, build one and begin talking about how you are chasing your dream of being a writer.
On that website, capture the email addresses of visitors.
Make a list of family members, friends, schoolmates, and business associates who might also be interested in your work.
When you speak at libraries or conventions, make sure that you add to your list every single time.
A week before your first novel comes out, email your fans and let them know. Then send a second notice on the day that it goes on sale.
