The most important thing for any con artist is never to think like a mark. Marks think they can get something for nothing. Marks think they can get what they don't deserve and could never deserve. Marks are stupid and pathetic and sad. Marks think they're going to go home one night and have the girl they've loved since they were a kid suddenly love them back. Marks forget that whenever something's too good to be true, that's because it's a con.
