It is not always easy to accept the loss and move on in gambling. It also depends on how much was used to bey. Some people do.not bey with what they can afford to lose. They stake very high and that is why it is always difficult for them to move on when they lose it. They will continue by chasing their losses by taking some revenge betting which never ended well.
When you gamble with any amount you can afford to lose and take gambling as a fun rather than an investment opportunity, you can always move on whenever you lose.
The main difference between those which gamble for fun and those which gamble to get money is their ability to move on once they lose, those which see gambling as just another hobby can accept their losses and then do something else with their time, but those which want to make it a profession cannot accept the fact they lost money, so they keep gambling hoping to recover what they lost only to face disastrous results as they gamble money they cannot really afford to lose.
That's what irresponsible gambler does, they lose one bet, and they don't react, if they lose two or maybe more, they will start panicking, and with mixed emotions taking their mind like a storm, they start doubling or increasing the bet amount so that they can recover the money they've lost in those bets from earlier, ironically, it works sometimes and they manage to get it back, but what happens is they try it again and they fail the second or third time.
A responsible gambler, even if he is not gambling just for fun, will never chase their losses because they already understand how gambling works, the more you try to recover your losses, the more money you are going to lose and that is not a wise decision. It's better to simply keep using the same bet instead of losing everything in a matter of a few minutes.
