Over your craps-playing life, you'll likely have more losing sessions than winning ones. Accept it. Remember, with craps, you must learn to live and play in reality, not fantasyland, or you'll go broke in a heartbeat.
Suppose, after two hours, the dice have whittled your chip stack down to $20. You haven't seen a hot roll in ages. Although losing is as much a part of the game as winning, you can't help but feel lousy. You wonder why you even bothered coming to Vegas in the first place. You were a rock for two hours, but it didn't work. You want to win so badly that you lose control of your common sense. You're down to your last $20 for the session and you have no fight left. Stop!
You must never capitulate, never surrender, never think, "This sucks, I'm going to put the rest on the Hard 4 and, if I lose, then I'll leave. But if I win, I'll be right back where I started." That's the dumbest thing you can do at the end of a losing session.
If you insist on giving your money away, please send it to your favorite charity. Don't give it to the casino. Occasionally, you'll win one of those idiotic bets, but don't think you'll win enough over time to conquer your losses.
If you can't accept losing, you have no business gambling. If you can't stomach losing a particular session, then quit that session and cash out. Don't pee your money away on a terrible bet hoping to hit it big and get your money back all at once.
If it's an awful session and you lose a lot quickly, then accept defeat and cash out with the $10, $15, or $20 that you have left. Take that remaining $20, go have a beer in the lounge, listen to the band. Put it in a nickel video poker machine and maybe hit a 1,000-coin jackpot. Put it in your pocket, find your wife, and spend time with her. Don't relent. Do something besides pee your money away on a losing proposition bet. Don't toss in the towel.
Now you know!
