There is nothing like controlling your emotion, people need to start making use of their senses and stop their greedy belief that they can pour all they have into gambling and go home with millions of dollars. Some people are so greedy and addicted to gambling to the extent that they lose their senses and start playing like fools. The way some of them be playing with confidence and acting like they know they are going to win and even use all their money to Play gambling, I'm always surprised. Gambling is all about risk and you should be aware of that. If you can't control your self and use your senses then you deserve whatever is coming your way.
I think there is, greed is still an emotion that people feel thus, controlling greed means controlling their emotions. Anyways, gamblers already know the advantages and disadvantages in gambling but they tend to overlook them because of greed, gamblers should be responsible enough with their actions and decisions because they are the only ones who can control and save themselves, we can give advise but they are the ones who can convince themselves to follow that advise.
