Passive income: NO

Becoming a successful book author and earning passive income solely from book sales is a challenging endeavor. While it is possible for some authors to achieve passive income through royalties, it is not the norm for most. Setting up automated systems like book marketing campaigns and outsourcing tasks such as editing and formatting can help streamline the process. However, reaching a level where income is truly passive typically requires a significant amount of initial effort and ongoing promotion. While there are success stories of authors earning passive income, they are often the exception rather than the rule. It is important to manage expectations and understand that passive income from book sales may not be easily achievable for everyone.
