As a responsible gambler, knowing that it's hard to win from gamble in other to make a living is very difficult, it will make you to know how to spend on gamble by risking what you can afford to lose. However, the reasons why a responsible gamblers doesn't spend more money on gamble is probably because they know that gamble is for entertainment and anyone that gamble excessively will become addicted and also end up being in depth.
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.
Some people like to drink when they are angry or depressed and some like to listen to music while some feel like smoking just to feel better but the important thing is drinking while you are depressed might worsen the case because when you are drunk you won't know what you are doing, and if you keep on drinking and gambling everyday, you will definitely become an addicted gambler or drunker.
Actually, reason for saying this is that it's not a good idea to gamble when you are drunk because you might exceed your gambling limit and also gamble recklessly. And as someone who's family responsibility is on him/her, when you become addicted to hard drugs or gamble the children and wife's (those who depends on you) will suffer because there's no other means of survival.
