Many years ago an East Texas farm boy struck it rich. A huge deposit of oil and gas was discovered on his land. One day he traveled to New York to meet with a high-powered stock-broker. The broker took the farm boy to Wall St. to show him the eight city blocks that mark the center of the financial universe. As they walked along the street the farmer suddenly stopped and said, “Wait.” He slowly moved toward a planter then quickly reached in and pulled out a cricket. The broker said, “That’s amazing. How could you possibly hear a cricket with all this city noise?” The farmer dug into his pocket and pulled out a handful of loose change. He said, “Watch this.” He dropped the coins on the sidewalk and everyone stopped to look. He said, “See. What you hear depends on what you have been trained to listen for.”
