There should be a time to stop gambling after win or loss depends on the situations and if you are using your profit again and again then neither you will make a better use of your profit nor you will enjoy this pleasure. Stopping duration is necessary in gambling and its not a waste of time but it is a time to enjoy and learn more.
It is easier said than done. No gambler can win in gambling and then stop gambling completely. It is not possible. Most people who have won huge amounts of money from gambling diversified by investing in other sustainable businesses and then gamble for fun still hoping for more wins. Remember money can never be sufficient. People who gamble all their winnings away are addicted gamblers and it is pitiful to hear that people who became rich through gambling still lost everything to gambling. Well, maybe it’s a case of easy come, easy go.
I agree with you on the need for a pause. Even when you are winning it is important to take a break so that you can channel your winning into something productive. This is important because if you continue gambling, you will end up losing all the winnings. On the other hand, when you are losing take a pause too because if you get emotional you will lose more and then incur an irreparable loss.
