Why not try it? Wake up tomorrow, and decide that all of your most optimistic hopes and beliefs are objectively true. That harebrained idea that you've been nursing is a sure winner, and it could deliver 12.5% returns with enough backing.

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...
