You are right. When one gambler will go for gambling in most cases he will face issues with the emotions. But if the gambler cannot tackle it then it is natural that he will face loss Or his losses will increase. If you gamble with emotions, you will make wrong decisions to win again and again, and in the end it will be seen that the amount of loss is much higher. So I think always should avoid emotion in these cases and go into a strategy.
The more you can control your emotions while gambling, the more likely you are to win at gambling. I think gambling can be done if you have the right strategy to win. If a person can't control his emotions while gambling, he will never win at gambling. I don't think you can. In order to win gambling, you must have a good experience with gambling and also have good luck. Gambling is easy as well as difficult gambling can make a person completely destitute and many people have become big people through this gambling.
