That word "moment" is key. One of the biggest giveaways that you might be part of a con is a sense of immediacy: You have to make this decision now. If a stock is a good deal today, it will be a good deal tomorrow. When you're dealing with any scheme that involves money, you should ask yourself two questions: Is it possible that this person could be lying to me? And if they are, what do I stand to lose? If the answers are "yes" and "a lot," take some time to investigate further.
Con artists are great at spotting our vulnerabilities. What's their biggest vulnerability? What kills them is that they can't tell other people how smart and slick they are. Eventually, they have to talk about it. Interrogation is my specialty. I get more confessions from con artists than from any other kind of criminal. It drives defense attorneys nuts! They can't understand why these people confess and then ask for a lawyer. But if con artists believe they have a sympathetic ear, someone who understands them, then they love telling you their story. They want to compare notes with you. They want to gloat. You know the old saying, "You can't con a con"? Well, I have proven that wrong countless times.
