They forget how much they were winners. They’re fixated on the one, big-time jackpot. So they’re like Felix the Cat who just keeps on walking. Well, we aren’t supposed to act like a cartoon character (even one whose name means “lucky”). We need to keep some of the money we win. But it’s that greed — one of the seven deadly sins. Greed always wants more and paves the road to Perdition (where the casinos are open all day and you can lose your soul if you keep on betting). It’s a fact of a gambler’s life that the House edge wins out in the end. The longer you play, the more likely it is that you’ll end up a loser.
