Through out your craps-wagering life, you’ll likely have more losing periods than winners. Go along with it. You must understand how to play in the real world, not in fantasy land. Craps is developed for the gambler to lose.
Suppose, after two hours, the dice have whittled your chip stack down to 20 dollars. You have not witnessed a smokin toss in forever. Even though not winning is as much a part of craps as being victorious, you cannot help but feel cursed. You wonder why you even thought about coming to Vegas in the first place. You were patient for 2 hours, but it didn’t work. You need to win so badly that you are deprived of control of your common sense. You are down to your last 20 dollars for the game and you have little oomph left. Leave!
You must never give up, never accede, never believe, "This blows, I am going to put the rest on the Hard 4 and, if I lose, then I’ll depart. However if I win, I’ll be back where I began." That’s the dumbest action you can perform at the conclusion of a non-winning session.
If you can’t acknowledge losing, you have no business making bets. If you can’t bear not winning a given session, then drop out of that game and call it a night. Do not toss your money away on a terrible wager looking to hit it big and win your $$$$$ back in one wager.
If it is a horrible day and you are deprived of a lot swiftly, then acknowledge defeat and take your money with the 10 dollars, $15, or $20 that you have remaining. Take that remaining 20 dollars, have a beer in the lounge, listen to the band. Play the money in a five cent electronic poker machine and maybe get a one thousand-coin win for $50. Keep it in your wallet, find your spouse, and spend some time with her. Do not give up. Do something besides piss your money away on a non-winning proposition bet. Do not throw in the towel.
