The author was once a professional card cheat. Drawing on personal experience, he tells readers that cheating at gambling is a path astray. No matter how glorious the winnings may seem, they cannot conceal the misery behind them. There are no achievements you can share with your family, and you cannot live in the sunlight like an ordinary person. Who knows whether the next game will cost you your life? Who knows whether friends who were brothers in all but blood just this morning might suddenly turn cold at the casino and set you up?
Through stories that truly happened to him, the author warns everyone who is tempted to take a chance: gambling is the source of all evil. Whether you are temporarily winning or losing, in the end, you lose.
