It is true that you say we must be careful in spending money, pay attention to every money spent from the income generated. Many people do gambling by forcing themselves when they run out of money and don't even have income, of course this is a problem, because forcing themselves to gamble is certainly not the right thing, because if we really want to do gambling we should have a clear income first. Do not force the situation.
If we have income or income it must be managed as well as possible, do not just have the income we can gamble excessively. Managing finances properly must be done because it is for our own good too.
We know where we allocate the income, and not just allocating the money to gambling. It's easy to spend the steady income we generated, but it's hard to manage the money. We have the ability to know where the money should go and how much money we left so that we can use it to deposit the money to our gambling account to start gambling. We don't have spend much money to playing gambling. Gambling is just for fun for us.
If we can manage the steady income well and filling all necessities, including allocating some amount to playing gambling, we don't have to break our limitations because we can use all the money we have in the right place. Steady income are means we have something that we can use to fills our needs, and we must manage it well.
