John is confused in his thinking and he does have mental challenges as you will see. I clearly told him that if he has $100 and finds a way to spend every last cent the same day, even on food, then it only ensures that he has not even one dollar for tomorrow. There are very simple logical changes one can make in order to improve one's own tomorrow, or next week.
Of course, holding on to paper bolivars in Venezuela would never be smart as they devalue to nothing by the next day, but buying a bit more sugar or cereal than you need in order to trade those the next day may work. Economy in spending is preferred more often than not. For example, I walked the ten blocks instead of pulling my ride out of the garage. I have the time and it is easier to think when walking.
Great comment.
