The necessity or compulsion that will prevent us from experiencing the effects of risk in gambling is to limit money when gambling, as you said, this is clearly true but will only be done by a small percentage of all gamblers. Because the temptation of casinos is so great, sometimes when we are careless we are easily influenced to bet there.
Yes, if we don't want to experience significant losses, we must try this step as best as possible because we will definitely experience the results with great happiness.
Limiting the money to playing gambling is one rule among many other rules that we must have when playing gambling. We must stick to the rules if we don't wants to gets trouble in gambling. Many people already breaks their own rules and can't survive in gambling and becomes addicted to gambling. The temptation of casinos will always be there but if we can stick to our rules, we will not tempted and will enjoy gambling as an entertainment. We can treat gambling as a fun activity and will not used much money because we don't wants to gets trouble. When we losses, we will not try to recover the losses because we knows that can makes us lose more money because that can related to the emotional that can increases.
We must remember that those online gambling sites, physical casinos, or whatever kind of gambling will remain there and just wait for us to go back. We cannot do that if we will waste it all in one day. What I mean is, there's always a time for them which is why a plan must be created. Limit ourselves to the amount that we can only waste for the day and expect that it will be depleted and make sure that we won't be going back to deposit again after it's all gone. If we win, that's cool, but on that event, we must also have a stop point. Because that's the problem with most gamblers, whenever they win they want to continue which means a chance for the casino to get back our profits.
Last time I hit the x500 again in Keno and I was so happy that I was online at the time it was hit. (not away from the keyboard) From there, I don't know what is next but I am hesitating to bet again. I could just withdraw and savor the profits, which I did. Control and discipline are important part of gambling.
