How to make money on the Internet... <- NOPE

Looks like the biggest business on the Internet is telling people how to make business on the Internet :-/

Hilarious. Looks like that is the biggest money source. Sounds like a snowball system. And back then they told me: "All you need to do is writing good articles to get money". Sure, and where does the money come from? You need a plan, right?
I mean ads or something. Or you write a PDF about how to make money on the Internet with just writing good articles and sell it via a paywall. Ridiculous.
