Yes, well I think that for many the main reason is not to fail their family, because there are many cases where players come and get paid l, they start drinking alcohol, go to the casino and spend everything, can you imagine the disappointment that their family will have if they tell them that they spent all their money in a casino? How would the wife and children of that person feel? Obviously they will not be a role model, and if they have no other income, how will they be able to solve it? It is difficult, sometimes things in the lives of others are hard, but basically in life there are always hierarchies that must be given the required importance, and family at least for me is my main reason for working hard without stopping.
