With controlling the mind, we can think about something wrong and something good, so if somehow we are in a bad situation or conditions, we can get a way to solve the problem. And related to the gambling game, if you can control your mind, you will not become addicted to gambling, and you will know how much money you use to gamble.
Mind game is one thing you have to be able to sort out first, which is always the center of attack most time when it comes to gambling impulses, but as long as you have been able to settle your mind with the idea that this is just a fun thing you are paying for and you even have the chance to decide how much you want to pay for it, and it sometimes even comes with incentives if you are lucky, you will not end up putting so much attention on things you should not.
