It's too easy to say "just be self-disciplined."
Nobody knows all his inner demons. We perfectly see the weaknesses of others and their examples from life are always obvious and simple for us, but in fact we ourselves have neither the ability to look at ourselves from the outside nor self-control. Imagine that you won a large sum with the first bet.
Will your inner state remain the same?
I wrote that it's better to keep friends around, or write down your limit, or have only cash. The next time I go to the casino, I will definitely follow these rules, because you need to be especially strict with yourself.
When talking about the issue of discipline or self-control in gambling, it is actually easier said than done because we know not only about gambling but in everything where theory is easier than practice.
But on the other hand, we also have to realize that even though it is a difficult condition, we still have to try to say it at least to be a reminder to ourselves that healthy gambling must be accompanied by good self-control and discipline.
In the end, it is things like that that make us able to minimize what we do at the gambling table.
