Sometimes I worry that self-publishing is going to overrun the publishing industry. There will be so many self-published new books that readers will never be able to find the best ones.
Sometimes I worry that Barnes & Noble will go out of business, leaving Amazon the last man standing.
Sometimes I worry that people no longer care about reading. That video games and movies and the Internet are robbing us of our greatest form of entertainment.
Sometimes I worry that ebooks are pushing the overall value of books down so low that people are more willing to pay for a cup off coffee that took little effort and no imagination to make than for a book.
Sometimes I worry that Amazon is monetizing books to such a degree that self-publishing is becoming less about writing great books than it is about writing as many books as you can so that you can make as much money as possible.
Sometimes I worry that I've achieved my dream of publishing right at the beginning of the industry's collapse.
Sometimes I worry.
And then I pick up a book like Eleanor & Park or The Marbury Lens or Marco Impossible or any of the hundred books I've bought in the last year alone, and I don't worry so much anymore.
There will always be an audience for great books, and great books will always find an audience.
