"Forbes ranked Perot's self-made quotient as a full-fledged 10. That's because he started his empire on his 32nd birthday as a one-man operation financed with $1,000 borrowed from Margot."

"Perot came up with the name Electronic Data Systems while attending Sunday service at Highland Park Presbyterian Church, where he and Margot have been members since moving to Dallas in 1957. He scribbled it down on the back of a pledge envelope. Perot became a multimillionaire when he took EDS public in 1968. In a 2018 interview, Perot Jr. described the family's dinner the night before the company's IPO. 'Dad said, "Now tomorrow, we're going to take EDS public, and a lot of people are going to write about the money that we have. But remember, none of this is important. The only thing that's important is our family and how we take care and respect our family. That's the first time we ever had a money conversation in the family. Then we watched Dad become the Bill Gates of the '60s. As I tell the children, Fortune said he was "the fastest, richest Texan ever."'"
