T. Boone Pickens amassed his fortune via a concept he figured out as a paperboy. He expanded his paper route from 28 customers to 158 customers by buying out other delivery boys’ routes. It was the same proven theory he used to grow his oil and natural gas business that in time brought him a net worth of $950 million by the time of his death in 2019 at the age of 91. In 2017 when he began selling off his assets, he put his much-loved Mesa Vista Ranch up for sale at $250 million. The 64,672-acre ranch is back on the market with a large price reduction to $170 million.
