Even if a book sells a million copies, it would at best reach a very small proportion of the population. The same is true for a mega-hit film like "The Avatar". Thus, the worlds that are presented by these creative works by necessity remain a minority experience.
When we cast our eyes on the elements of every day, we find incredibly rich multitudes of experience that are the true "bestsellers" of life. Consider the sensation of flavor and taste as you sip your coffee in the morning. The joy of being immersed in the morning sunshine as you venture off into the wider world from your domicile. The swelling feeling of joy as you finally put your self at rest on bed after a strenuous day. These elements of experience are known to everybody, and shared by a true majority of people.
When one is young, one is often quite taken by a work of human creativity that one encounters. Because one is carried away, one sometimes even equates the weight of the adored piece with the whole world itself. One talks about the genius of the creator in a heated manner, enthusiastic on becoming an evangelist of the value of the work. One is then often disappointed by the more or less subdued reaction of the listener. One has forgotten that no matter how important a piece of creativity might appear to be, the experiencing itself remains in the minority.
Despite the disappointments, the young person soldiers on. One gradually rediscovers the common grounds for every breathing soul on earth. The simple joy of sharing those rudimentary elements of living must then serve as the foundation for communication. One leaves one's Dostoevsky and Murakami and starts to read the great book of the world once again, as one used to do as an innocent infant.
