Attempts to return the lost will only aggravate the position of the gambler and he will leave even more of his money in the casino. It's like chasing a shadow: the more you lose, the more you want to return, and this gives rise to new losses. A vicious circle of player addiction from which it is almost impossible to break out on your own, if it has already come to this.
In gambling, you can't let your emotions take over. Either stick to the strategy and increase the deposit, or act thoughtlessly and drain the entire deposit. That guy's story on Reddit is a case in point.
It is true. It may be difficult to keep away from it once it is done. Chasing losses had always been the main problem of any gambler, it's the ego that tells us that we must win no matter what and this is the reason why gambling businesses will just keep on piling up. They know the incoming money from this industry is a nonstop cycle too due to the fact that gamblers tend to like having their revenge once their losses are soaring.
There must be a game plan. A strategy. A budget. All of those will play a big role to keep one gambler's discipline intact. Bring only what you can afford to lose but with how accessible gambling platforms are today, it must be harder for them to keep the discipline. It's always open, there's no such thing as closing time.
