This is a YouTube video titled "How I make $10k mo as a self published author" containing a monologue by a single speaker discussing their experience and earnings from self-publishing books on Amazon, explaining the passive income model and profitability of different titles.
I make over $10,000 per month passively from my self published library of books. Some, like Confessions of a Teenage Gamer are books I absolutely loved writing, but don't make me very much money. I probably spent two or three thousand dollars publishing this and it's probably made me five or ten grand in profit. Others, like the art and business of online writing, make me a lot of money. This book alone over the past three years has made me over a quarter million dollars in royalties. And the truth is, creating a library of self published books isn't hard. Anyone can write a book, and anyone can hit publish on Amazon. And every day, whenever someone buys one of these books, Amazon prints it on demand, extracts the printing cost from my royalties, mails the customer the book, and then cuts me. It's awesome.
