James Keyes, who spent over two decades at 7-Eleven, served as CEO from 2000 to 2005. As CEO, Keyes told Business Insider he had long workdays and slept around five hours a night. "Basically, a big portion of the CEO's job is communications," Keyes said. So, if it wasn't a sampling day, he'd usually have a salad brought in, and eat it between meetings. He'd usually start winding down by 11 p.m., spending the last hour of his day reading materials in preparation for the morning.
