Stop buying Money Making ebooks.
That shit doesn't work, they make money off you. Yes, granted some of them actually can make money, if you devote your whole life into it, requires time, capital, pyramid scheme, unrealistic effort. Sell a book to desperate people trying to make money, while you make money off of them. Save your money, they're just ebooks that are recycled throughout the community and leaked.
