When payday arrives, I usually only buy monthly food supplies for my family and sometimes I take my family out to eat. So, I think what I did was not an act in vain. Because I personally think buying food supplies and occasionally taking the family out to eat is very important. Maybe you could say I spend a lot of money after payday. But I only buy and do things that are truly important to my family. So basically I don't waste the money I have on things that are unnecessary or useless. And I have calculated all the expenses I incur in such a way. So there is no wasted or useless spending of money.
