" Nothing moves forward in a story except through conflict. Writers who cannot grasp this truth, the truth of conflict, writers who have been misled by the counterfeit comforts of modern life into believing that life is easy once you know how to play the game.
These writers give conflict a false inflection. The scripts they write fail for one of two reasons, either a glut of banal conflict or a lack of meaningful conflict. The former are exercises in turbo special effects written by those who follow textbook imperatives to create conflict but because they're disinterested in or insensitive to the honest struggles of life, devise overwrought excuses for mayhem. The latter are tedious portraits written in reaction against conflict itself, these writers take the pollyanna view, that life would really be nice if it weren't for conflict.
What writers at these extremes fail to realize is that while the quality of conflict in life changes as it shifts from level to level, the quantity of conflict is constant. When we remove conflict from one level of life, it amplifies ten times over on another level. When, for example, we don't have to work from dawn to dark to put bread on the table, we now have time to reflect on the great conflict within our mind and heart or we may become aware of the terrible tyrannies and suffering in the world at large.
As Jean-Paul Sartre expressed it, "The essence of reality is scarcity. There isn't enough love in the world, enough food, enough justice, enough time in life. To gain any sense of satisfaction in our life we must go in to heady conflict with the forces of scarcity. To be alive is to be in perpetual conflict at one or all three levels of our lives. "
