Greed exists in every individual. it might be easy to say not to be greedy. In practice, for example, let's say you get a jackpot when you bet. did you stop then and there? definitely not, your mind will say try again, who knows, maybe you will get the jackpot again or at least you can get more than just now. that's greedy. It's difficult, but it's the main trigger for losing when gambling.
Yes, I don't deny what you said, that it is not easy to do, it is true what you said, it is very likely that if I get a big jackpot, maybe I will gamble again and that is a normal thing and what it is. will be experienced by many other gamblers. but at least I am just giving advice to other gamblers that if they can control their greed then they will be lucky later.

We don't wants to gets or feels the big lose so we will not lets ourselves tempted of gambling, especially playing gambling excessively because we already see what the impact that we can gets.
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.
