Let me say it simply: all you need to get published is a book that someone in the publishing world thinks will sell to the public. You don't need to be a celebrity. You just need a book that will sell. Yes, it is surprisingly hard to do that. It is hard to write well. Harder than most people think. It takes time to find the person who will believe in your book. But that's all there is to it. There isn't a magic code word to get past the gates. There are no gates.
Write. Don't waste time and energy believing in conspiracies that don't exist. Don't spread them around the Internet and mislead other writers.
