Yes, it is the madness of a gambling addict that will destroy your life and that of your family. I also have a friend who works hard but unfortunately he spends his money just to gamble. He is not married so he has no responsibilities to his family. But he had debts and that was also used for gambling. His hard work is just for gambling. It's a shame because it means he has ruined his future. It's a shame when he spends his money on gambling instead of investing.
A person like that will be very difficult to recover, especially if you invite him to invest when he has money from the results of his hard work. Or it could be that he is addicted because he has won several times in large amounts so that he starts to be willing to spend more and more on gambling without making a more careful calculation of his own finances. And people who are addicted like that usually don't really think about their own future because their minds are only focused on gambling and gambling.
