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.
It's easy to say but difficult to do.
Yes, all of that is true and I also doubt that someone who is very easy to say be disciplined will not be able to control themselves, even when they get a big win someone will not easily stop gambling and leave gambling but instead will continue betting in the hope of winning bigger and without them realizing that it was the beginning of the defeat that awaited him.
Just imagine when someone says discipline is very important and it is very surprising that he gets a big win and in 1 hour he loses it all because he tried to stop but couldn't which is caused by greed which always defeats all discipline and for me there are only 20% of gamblers who are disciplined .
