"People are stupid; given proper motivation, almost anyone will believe almost anything. Because people are stupid, they will believe a lie because they want to believe it's true, or because they're afraid it might be true. Peoples' heads are full of knowledge, facts and beliefs, and most of it is false, yet they think it all true. People are stupid; they can only rarely tell the difference between a lie and the truth, and yet they are confident they can, and so are all the easier to fool." (Wizard's First Rule, page 560)
Turn off your computer and go outside. Is that enough truth for you?
Do you need to go and find another youtube video that explains exactly how to 'go outside'?
