The problem with many players is that they don't understand that there is a very fine line between how exactly one should react to losses. Some get even more excited about this and want to prove to themselves and others that they can win like other lucky players. This should never be done, because the game turns into a game with your emotions and feelings. In general, it is difficult for me to give advice on this issue, but I know exactly what should not be done because I have gone through this path myself.
Indeed, that kind of thinking brings them to much deeper engagement to gambling unable to control situation made them mistake in taking tough decisions, emotions once dominated inside a person's mind the outcome mostly negative though in some chances if luck really permits then it can come out with decent money.
But not all can manage to do that, emotional control is the tough one to beat as it's you against yourself when you are in sessions.
