If you have won multiple times in the beginning, you should take a break and start gambling again. However, if you are gambling just for fun, then it is a different matter and you can continue because your main goal is to have fun. However, those who are new to gambling initially have good luck and winning acts as a trap for them. In this case, if you cannot control yourself and continue to bet even after you have won multiple times, you may face losses or defeats. You will never win multiple times in a row. So you decide for yourself whether you will continue or stop for a while.
Even for those who are gambling for fun, they also need to take a break. It's not as if gambling is the only thing that could be done for fun; they can also focus on other things because the more time they are spending on gambling, the more they will also spend much more money as payment for that fun, and there is also how they will spend too much time doing one particular thing, and the thing will later turn out to be boring, or something else will start keeping them from continuing to play and not be fun again.
I really don’t think there is anything wrong with taking a temporary break from gambling. In fact, sometimes it is actually the smartest decision you can make because gambling is not going anywhere.. Gambling requires a clear head and a lot of discipline, and once you start feeling tired or pressured, that is usually when mistakes happen. Taking some time off gives you space to refresh your mind and then come back with sharper focus and better decisions.
And I agree with what you said about, anything done too much without balance eventually becomes boring or even harmful.
