Robert T. Kiyosaki has found the winning formula in the bestseller game. His blockbuster Rich Dad Poor Dad (written with Sharon L. Lechter) has had, as of this week, an 81-week run on the charts. The Warner edition has 1.7 million copies in print and there are about eight million copies worldwide. His newest, Retire Young Retire Rich, hits the trade paper chart in the #7 slot with 200,000 copies. His media dance card is full, so those numbers are headed north.
