With gambling we don't know when we'll loss control. If we're on the winning streak we'll have the patience to think and we'll place the bets. When we're on the losing streak the mind always thinks about recovering the loss. By this time we should've got the control to take a break, but most of us get triggered and multiply the bet value. This at times recover the lost fund and most of the time loss used to be the end result. Having limit on spending unlike win/loss used to be the best way to control ourselves.
Disagree with the first part of your statement. The reality in gambling is not like that.
It's not just when losing but didn't you know that when winning, it's more giving a gambler to bet more since why the hell they should stop if they are winning? You think that when winning, gamblers have patience but in reality, they are falling more on the spell just to continue to gamble no matter what since they are lucky that time. I admit that when I'm winning, it's hard to stop.
It's hard to follow when we put a limit. When winning, we won't think of stopping completely or taking a break. When losing, we still don't want to stop because we want to chase our losses. Where we will end up now? It's really on us where to stop regardless when winning or losing.
