That is what winning leaders are made of.  Be it Jeff Bezos, Paul Getty, Ben Carson or Larry King...or Sam Walton. Times may be different and geographies may vary but the message behind each such aspiring story continued to be the same. As times change, markets changed and so did people's expectations change with the changing times. However, the reflective flexibility these icons showed to be ready to make alternate routes when their defined paths were blocked, made them subsequently the leaders of the new markets when these markets finally evolved. Never forget that Amazon was established to sell books on line till he experienced mindless other opportunities when on-line book sales flopped.
