We once talked about success and failure, during which time he relayed what someone in India had said to him: “Only if there is a large problem is there a large opportunity.”

Roux laughed out loud, which he did often, and then said: “Isn’t that wonderful? That is now my auto-signature at the bottom of my emails from my iPad, because I think it is so valid.”

It’s a maxim he lived by, and which helped him build an industry. And as a result, the legacy he leaves behind is enormous.
