Suzana Keller's life changed when she was 14. Her hometown of Sarajevo – in what was then part of Yugoslavia – was suddenly the center of a civil war. She and her family became refugees and soon found themselves living in a single room.
So at 17, she took the opportunity to study in the U.S. and quickly learned that life was not everything that Beverly Hills 90210 had made it out to be. But she went on to graduate from Louisiana State University (in less than three years because her family couldn't afford more years of tuition) and joined consulting group Ernst & Young. Now the chief procurement officer for Coca-Cola Bottlers' Sales and Service, Keller says she set herself a rule.
"Whenever [supervisors] said, 'Who wants to do X, I'd raise my hand, and then I'd figure out how to do it," she said.
Women, she added, often don't want to speak out "unless they are 200 percent certain that they're correct. Men have no problems saying yes and they don't know what they're doing."
"Be brave because you all are brave," Keller added. "I'm not afraid to fail. I don't make the same mistake twice. If I make a mistake, I say that's on me and learn from it."
