Having some limits and following them up can make wonders in that regard. It's hard, but it's worth it.
I think that in a casino the only thing we have to limit ourselves is money, because emotions and impulses, despite how much we try to limit or control them, at the end of the day we end up giving in and that's not bad, it's just not advisable, for me it can be a very bad way not to express our emotions, our impulses, it's a game, but yes, doing it with limited money, because if we don't have control over our money, then it will all go away, and without money it is something that I do not recommend being.
