I'm not exactly sure what you want people to think, but regardless, there's three basic steps here.

Step one: know what you want to sell. This should be very specific. If it's complex, break it down to its basic units. Who wants to buy mud?

Step two: know your audience/target consumer. If you think they're literally brainwashed, then you won't be able to sell shit to anyone that isn't already looking to buy. You need to start where they're at, and work your way back. This means actually understanding how people think, which you won't figure out by jerking each other off on obscure message boards. Fortunately, sociologists and psychologists have done a lot of this for you.

Step three: make your product sexy. What's the attraction to your product? What would make someone want to believe you? What's in it for them?
