From my 2nd book:
“A movie studio will fund ten movies. A book publisher will fund ten books. In both cases, the producers or publishers often have no idea which one exactly of the ten is going be successful. In fact, they might be lucky if one of the ten is successful. Since they don’t know which one is going be successful, they still have to fund all ten. If nine of those books aren’t successful, well, the publisher is only going to print a small batch to begin with — that equals a small loss. If those movies or books don’t do well, fine. They’re done. The companies cut their losses and get out. However, the movie or book that does really well, the tenth one, pays for the losses from the nine losers. [Trend followers] think of themselves as the publisher, the movie studio, or the casino ‘house.'”
Not everyday talk.
