One of the most frightening things for "regular" human being is empty, white sheet of paper an pencil in right hand. What to put on it, without the security and privacy of my mind? That fear is the reason we do not see too much good texts, not only nowadays, but during the whole human history.
But, fools do not know fear. They write without fear.
And, fools are in majority. They recognize easy what is written for them. The demand is created by affordable supply. That is how circle begins. After that, it is easy to say that the world goes round (fueled on money and intelectual pornography)
