This sounds crazy, but bear with me on this one. If a wealthy billionaire told you he would write you a check for $16 million dollars if you counted every grain of sand on his private beach, would you do it? Furthermore, he has the checkbook and fancy ballpoint pen right inside his hands just in case you don't believe his words. Even more, he'll give you half that amount ($8 million out of the $16 million) when you reach the halfway point.
