Gambling is just a way to have fun with enough money so we don't have to risk more. We need to have rules in gambling to prevent from losing money and becoming big. If that happens, we may stress thinking about our losses.
The best thing is to have budget of gambling, for instance if we are working and are being paid on monthly basis or weekly basis we should have that thinking that we have to allocate specific amount to our gambling account to help us to gamble throughout that month or week. This could be either 1-10 percent of our monthly income dedicated for gambling for instead of having double thought about the amount we are using to gamble this could cause so much trouble to the said gambler because already their heart is already being disturbed with the amount they loses from gambling since they don't map out specific fund to gamble it becomes something to think about and even if they decides to chase their loses it would also lead them to more loses.
