That is how many gamblers have be addicted to gambling because, they refuse to reject that spirit that is telling them to increase the amount they have fixed to play the bet and when they miss the bet, they will be thinking where to get money to continue the gambling that very day because they have entered what it will take them some years before they will be free for such habit.
That is just the main effect of gambling. If you just allow yourself to be overwhelmed with the profit to gain in the game, you will always listen to that voice that will tell you to add more so that you can get a lot of profit, and if care is not taken, you will end up risking all you have just to gain that win that you are waiting for, but there is a factor that I discovered that causes all those additions for most people.
The reason I say so is that I have even met a gambler who gave me his story of addiction. He said he started getting addicted to gambling. After he won a hug amount of money with the smaller bet, which if he had put more, he would have gained more than what he got, so after spending the money, he started putting a hug amount, not minding even if it was depths or a loan, which he always lost the game, so now he is regretting I think this is the same thinking that came to people's minds when it came to such a case.
The spirit use to come to my mind whenever I want to play a bet and my mind will be telling me to increase the $5 I use to gamble everyday to $10, but I use to ignored such spirit because my daily budget for gambling every day is $5 and the moment the $5 didn't bring good results from the gambling, that is the end of my gambling in that whole day .
Sticking to your budget is the best thing to do, because if you are not that sticky, you might end up in the regret zone, like the story I gave above, but to be sincere, a budget is just the best solution to follow to defend yourself from becoming addicted to gambling; if not, the case is different.
