Correct. Gambling responsibly is very necessary, especially if we are a husband or head of the family. think about how we really make gambling with limits without having to lose a lot of assets which puts our small family in danger because assets continue to be sold because of the addiction of gambling.
I don't know what does "head of the family" mean, but you are right about this: if we have people that rely on us, we shouldn't let them down. We should drink responsibly because as overdrinking is not only bad for the health, but for our budget too. Same with gambling. Excessive gambling is bad for our mental health and it's usually bad for our budget.
The head of the family is man who has a wife or also has child and is fully responsible for all the needs of life shelter and education for the child and that is why he is called the head of the family because of that responsibility man who has having family must be able to minimize all activities that are detrimental or cause the family to fall apart if they take wrong actions such as in gambling.
Of course everyone who is responsible for their family is not advised to do excessive things especially if they use their finances for gambling because the needs of life and family happiness are the priorities of husband or father.
Discussions like this have actually been presented here lot but unfortunately they cannot cover everyone out there so there are still many cases of family destruction due to mistakes in managing time and finances for gambling.
