If you only use a small amount of money and it doesn't last long then you don't need to rest, but perhaps what our friend @seacoincollector means is that when someone gambles for a long period of time and experiences consecutive losses then someone must immediately stop and rest because If you continue, you will experience more losses or you could go bankrupt. There are some people who think that if they continue their gambling sessions even though they are losing, maybe over time they will be able to recover the money they have lost, but they are not aware that gambling is starting to get into their minds, making it increasingly uncontrollable and ending in continuous defeat.
In fact, in my opinion, taking a break is not only about going to the bathroom, eating etc. but also about resting our minds from the negative side of gambling and being able to relax ourselves from emotional feelings. Stopping your gambling for a while will lead you to wiser thoughts if you are calm. You can also be responsible in gambling and not be filled with feelings of regret due to losing because it has become part of gambling. This will certainly make your gambling more enjoyable.
It is true that if we have experienced a series of defeats then we should stop and rest to calm our minds, which if we continue it will also trigger our emotions which can make everything get out of control, which will most likely happen when we can't stop. in gambling there are big losses such as losing large amounts of money or going bankrupt as you said. this triggers big problems that can destroy our lives, so as much as possible we must be able to control ourselves well, have clear thinking and have limits in gambling which is important, because to avoid and prevent big losses it depends on us, if we can control everything well then it is likely that no major losses will occur. Now that there are so many cases of big losses, it means that there are still many gamblers who are not smart and clever in their gambling, they tend to only think about winning while not paying attention to their fate. Even though we should be able to avoid problems that have occurred in many cases, I also think that with the many cases about the bad effects of gambling, we can use it as a lesson for ourselves so that we don't gamble excessively, which is not a good thing.
That's true, indeed we can take breaks that really calm our minds, such as meditation or other things that we think are the best things to calm the mind. Taking a break from gambling is a must because it calms your thoughts, which if you don't take a break will have fatal consequences.
