Whether you're gambling for fun or you're gambling for the profit involved there's a point you would have to give yourself a break. On a norms excess of anything is wrong and this includes gambling too. Yes, it could be boring too when we overdo a thing and by taking a break it helps to relax and think of more better ways to enjoy the games when we go back to it. It also can give us time to fashion how we spend our funds to not overspend out of fun.
That's right, entertainment isn't limited to gambling, so it's okay to occasionally spend money on different entertainment, or at least spend all your free time with your family. Gamblers should have a specific time to rest, just like those who enjoy betting on sports, when the season ends, it's a good time to take a break.
Besides managing your spending, you can also learn or update your gambling strategies to increase your chances of winning. I think that continuous gambling can lead to boredom, or vice versa potentially lead to addiction. Therefore, I strongly agree with taking time off, regardless of whether you're winning or losing in certain time period.
