I have had two clients who have fallen from fabulous wealth and rarefied success to abject poverty and searing shame. Men who allowed their positions atop the human hierarchy to deceive themselves into thinking that they were affixed there for eternity: heroes of their private Rushmores.
Both built and ran major businesses. Both started from scratch and propelled themselves to the apex. Both were risk takers–the way all fire eating entrepreneurs are– and both made the intoxicated mistake of betting the ranch and watching the dealer remove all of the chips from the table when they lost.
