I think managing money doesnt fully dependent on salary,because if you have habits like gambling or drinking then you cant even manage high salary and one can manage small salaries as well if he spend carefully.
Well i think it will be still depends in you how to manage it.. even you have habits like drinking or smoking it can not affect it a lot but in gambling it can be affect to you that can be trigger to deposit more and gamble again..
So its not a good idea.. its still good to save your salary from your partial salary in your job so that you can use them in the right time.
Whatever makes you happy you have to do it, we will just live once so we have to live to the fullest as they say. However, it is not right to spend more than in our budget as there are things that we need to prioritize and that is our needs, our wants will just follow when there's an extra amount left and IMO drinking liquors and gambling is your wants so stick with the budget..
For me not all the time we need to consider our family we do not need to be happy just only our self, and most of the people are thinking for the future of our kids before our own happiness. That is why we need to manage our money to have savings for their future.
