Innovators and visionary leaders don't need to "know any of the facts" about their business, ESPN founder Bill Rasmussen says. It's always possible to find technical staff to handle the details, as long as you've got a vision to guide them. "I don't know how television pictures fly through the air, but I've been fairly successful in television," he explained. "I don't have to know all that technical stuff. You just have to have the vision and the passion."
