Spend as much time as possible poring over books published by major houses. Study their design formats, including title-page layouts, table-of-content styles, and presentation of copyright information. Aspire to excellence for every book project you choose to undertake. Learn to write brief, effective press releases — which you’ll include with every book you send to editors, publishers, and critics. Develop a social-media marketing plan. Become savvy on Facebook; learn to tweet. Create a website. Open an account with a company like Square, which allows you to take credit card orders.
