Should we be disciplined in gambling, does it mean that we are better at gambling, or that we put less money at stake with more enjoyment, less fear, adrenaline, etc. ?
When we implement morality and other stuff for your kids you will teach them the qualities of life and discipline means you live a pious life without hurting anyone and have a good life but what is discipline when it comes to gambling the only thing that comes to mind is never to gamble with the money you cannot afford and there are many assholes who take a loan and gamble the money.
