I am usually very careful with my expenses, for before getting paid I am already doing the calculation of all I am supposed to pay in a month. After calculating all my monthly expenses I see what I have left, and then I also try to predict how much money I am going to spend on a certain month. Some people might ask: "How is it possible?" Well, you just need to consider if in a particular month there will be some bills related to something like buying birthday gifts for relatives, or if you will need to travel to spend a weekend in a place on leisure or business. Anyway, I consider myself the kind of person who doesn't like to spend too much money on things that are not useful or things that are not going to be necessary for me, but once in a while it feels really good to treat myself with something nice, just to make sure that my money is not just for paying bills, but also to do whatever I want and whenever I want too.
