It will not be treated here of the quality of fluid because the fluid is defined as a quantity. It does not accept the concept of quality in the same way as water, defined as H2O molecules, is just pure water. What comes out of a tap is water plus other component that, mixed together are qualified of good and bad. But water is just water.
It will not be treated either of the quality of the action fueled by the fluid. It could be discussed for many hours of the respective quality of "playing videogames" against "reading books" and I am sure that countless philosophers would be more than content to write on the subject.
It will be discussed of the quality of the focus, regarding to the apparatus that gives life to it. As we must spent close to the total amount of our dailly fluid in order to live a balanced life, we will now look upon the different ways that there are to spend it, and see how they affect our fluid-focus system.
Let us call "constructive spending" an activity that will bring to a person a feeling of "doing the right thing". For example, volunteering for cleaning a beach recently soiled by a black tide. Let us call "destructive spending" an activity that will bring to it's maker a feeling of doing the wrong thing, but he does it anyway. For example, beating up his dog.
And, saying that, we are assuming that the subject does have a sense of conscience.
No term really needs to be defined for an activity that will not affect the fluid-focus apparatus of the subject. And that represents the bulk of one's lifetime activity. It includes all hobbies, all remunerated occupations, all consumption of culture... and more.
For a person with no sense of conscience, of course, nothing would seem to be "right" or "wrong". It is believed by the writer that the sense of conscience is learnt, or not, during life. That it is not innate, or part of human nature. Then conscience can be define as what give a positive or negative value (in units of fluid) to a focus-requiring action. A weak conscience would give lower value than an accute one, the later giving a significant value to more actions than the first.
It seems to the writer that when the sum of constructive spending (counted in positive fluid units) and destructive (negative units) of one's recent activities is negative, the fluid-focus apparatus will be impaired by it. A person that activity would be mostly negative (T.I.T.S. counted in negative fluid unit) would see his efficiency in focusing decreasing. It is like the feeling of guilt refills the fluid reserve of part of the fluid it spend doing the incriminated action.
