Publishing books can be a powerful way to generate passive income that lasts for years and, in some cases, even beyond the author’s lifetime. Once written and published, books in print, eBook, or audiobook formats can continue to earn royalties without requiring ongoing effort from the creator. This makes it a unique asset, as it not only provides a steady income stream during the author’s lifetime but can also be passed on to heirs as part of a lasting legacy. With platforms like Amazon Kindle Direct Publishing and print-on-demand services, getting started has become easier than ever, making book publishing a viable long-term investment.
