I agree that responsible gambling requires recognizing when you're going off track and knowing your limits to avoid excessive spending. However, I also disagree because once someone is already addicted it can be extremely challenging to regain control and simply recognizing the problem might not be enough to stop them from spending more than intended.
And since preventing a negative outcome is easier than dealing with its aftermath then we need to make sure to never fall into this pattern of behavior, and quite honestly it is not really that difficult, just set a budget of how much money you are willing to gamble each month and you can also put a daily time limit so you do not spend too much time gambling, if you do this and respect those limits you will find out that you will always be in control and it will be almost impossible to gamble irresponsibly this way.
Quitting can be very difficult for those that had since gambling as a way if survival. There are part of the world that gambling is the only way for people to survive since getting a better job with good pay can be impossible unless one has the connection of the job. For those that attached emotion to gambling, it can be very difficult for them to quit since they might find it impossible or difficult if they make a decision that would crumble there means of survival. Things are really hard these time and with no hope if it getting better, all we have to do is to stick to what works for us until we see a better way for us to escape out of penury.
