Sure, people will disagree with you about how much things cost, or when payments are due, or the terms of contracts that you signed.
But if you're patient, you will eventually find people who'll readily believe a friendly smile and a dollop of gish gallop. They give up money easily, and they will often defend obvious cons once they have skin in the game.
You'll always be looking over your shoulder, though, waiting for the other shoe to drop. Your brain will know the truth, even if you try to suppress it, and the gap between expectations and reality will only grow with time.
Would you really want to live like that? Maybe for a day, I guess...
That's only a problem with people who force themselves to have that mindset. Some people probably honestly believe their own hype. Those are the people the poster wanted to be, the ones surprised when their cons blow up because they were blissfully thinking they were that brilliant the whole time.
