While we cannot know with absolute precision the day-to-day life of our remote ancestors, such as those who lived several centuries before us, we have enough evidence to imagine that they had fewer opportunities to distract themselves from their obligations, either job or of the study. In the absence of the Internet, with its unpredictable and inexhaustible leisure options, it is likely that people will not waste their time in activities that do not interest them: do not forget that it is possible to get carried away by photo galleries or funny videos to the point of losing a whole afternoon without knowing what we have done.
All this leads us to the recipe to postpone the urgent . What must happen so that we stop doing something of utmost importance? First of all we must think about the point of view: it is possible to ignore an obligation that matters to ourselves, or one that is of interest to a third party. In the first case, there is the possibility of to betray us the memory or that a defense mechanism acts in us that helps us move away from an activity that we dare not abandon. When the obligation benefits others, if we do not fulfill it on time it may happen that we do it conscientiously or may our brain play tricks on us .
The case of the word cannot be postponed It is particular in that it does not have well-defined antonyms: how to name those obligations that we can breach, or those commitments What can we break without problems?
