Elizabeth Prior knows how to manage stress and insecurity. As a resident of New Orleans, she endured Hurricane Katrina and its aftermath, spending months moving around the country, living in hotels and with relatives. Upon returning home, she got married and helped her husband finish up med school. Then there was the small matter of her applying to business school. Now in her second year at MIT Sloan, things are relatively calm for Elizabeth as she sets her sites on a career that makes a positive social impact.
