Greed and misunderstanding are the only things that can make a gambler feel this way. Some gamblers believe so much in themselves that they think they can recover any money they have lost by gambling.
The problem with gamblers is that they are not being realistic about gambling; they approach it with just their own understanding. That is why they think they can gamble without realizing they are harming themselves even more.
You're right, there are gamblers who think that they have gone roo far in gambler and for that they know how to go about the gambling thing in the aspect of getting back their loses but thats funny because, if as a gambler, you weren't able to win earlier, you later think that you can win all your lose may be because of the deceit in your mind then serious losing awaits such gambler, the best way to go about gambling is by allowing by gone to be by gone, letting go of the past, concentrating in things that are about to come nothing more, not all gamblers falls to this cheap trap, I believe that there are many responsible gamblers out there who won't dance to this tune.
