From every money one receives or get, not all is yours, because you will buy things that will be needful, very import, those not necessarily important and those that are of no need to buy. In every money received, the one that is kept is my own, while the rest are to be used for life's needs/wants. Because it is to be used, it has to be for something that are of necessity, and not for luxury when you know your income worth. Though, one may want to applaud him/herself after achieving a certain goal that was set before-hand.
It is okay to spend, but only when it is necessary to do so, and not for a show-off thing, because you want to prove to some folks that you don't know how they go around their financial life.
