In gambling, we have fun and gain profit at the same time. It helps to make a decision when we can continue and when to stop. Even it is too risky to bet an amount of money, we feel excited every winning on it. We know that gambling is about winning and losing, we learn how to control ourself to lose more money.
Not all of the time we could make profits and have fun at the same time in gambling, it is all about our luck, if we are going to be lucky on a certain day, then that is fun (obviously) but if it is not, then I'm sure you'll be annoyed or mad, and only few gamblers do have control on themselves when they are gambling, most of the gamblers are greedy and what they all want is to win more money.
