There are a number of reasons why self-publishing may be a better option than traditional publishing for some authors. Self-publishing offers more control over the final product, including cover design, interior design, and format. Authors also retain all rights to their work and receive a larger share of the profits. Self-publishing is also generally a quicker process than traditional publishing, so authors can get their books into readers' hands faster.
Of course, traditional publishing has its own advantages, including access to professional editing, marketing, and distribution channels. But for authors who are willing to put in the extra work to self-publish their books, the benefits can be significant.
