Rewrites are very important for making sure authors hone their work to be the best that it can be. Producing just a single draft or iteration of a book is not realistic. Editor and ghostwriter Deanna Brady recommends putting your manuscript away for days, even weeks if needed, and then revisit it with fresh eyes. Once your revisions are complete, give it to other people to review - friends, relatives, former teachers, writing peers. Then, if needed, hire an editor for the final review. An editor will find any remaining errors, omissions, or inconsistencies, and can help take a book from acceptable to wonderful.
