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.
