The stigma of self-publishing is gone. The physical quality of self-published books now rivals that of traditional publishers, while the content of self-published books is obviously far more erratic. The cost of self-publishing has made the process democratic and appealing to not only those who are unable to secure a traditional publisher, but to those who recognize that one is longer a requirement to gaining and building a loyal readership.
The list of authors who have self-published their work through the years is impressive. Marcel Proust, Nathaniel Hawthorne, Virginia Woolf, Edgar Rice Burroughs, Jane Austen, Gertrude Stein, e.e. cummings, Henry David Thoreau, Emily Dickinson, and Dave Eggers, among countless others have all self-published their work at one point in their careers. If you are seeking a traditional publisher to validate your creative work, you are missing the point. A rejection from a traditional publisher is not necessarily a comment on the quality of your writing. It is simply a comment on how much money they believe they can make from selling it.
You will get to keep a larger percentage of the pie. You just have to decide whether the pie will be appreciably larger than with a traditional publisher and how much promotion you are willing to do.
