Thinks that desire we call simply D, which to the inconveniences which brings you satisfy the desire to call G (by expenditure) and that a moment of happiness is when you can enjoy without feeling evil by what is costing you, i.e. “zero” (0).

But as always happens, your friends look at you and that makes you jealous, he sometimes also wants to go out with his friends and that leaves you alone one Sunday when he goes to court, besides your MOM you insists that “that boy, as neither working nor studying, don’t want. Molly Adams has much experience in this field. Call all these disadvantages together G (spending). You are happy when the pleasure of being with him neutralized to the effort that costs you retain it.
In algebraic terms this would be so: D G = 0 (I wish less spending equal zero). In this wonderful situation, you feel that you touch the sky with your hands and don’t have all the disadvantages that brought you or that you will bring into account. Why I say that happiness can be represented by zero, which in this case means ‘perfect balance’. It is this balance that causes you the feeling of happiness.
