Any time anyone tells you that a dream is impossible, any time you're discouraged by impossible challenges, just mutter this mantra: Tererai Trent. Of all the people earning university degrees this year, perhaps the most remarkable story belongs to Tererai, a middle-aged woman. When you hear that foreign-aid groups just squander money or build dependency, remember [her story]. Tererai was born in a village in rural Zimbabwe, probably sometime in 1965, and attended elementary school for less than one year. Her father married her off when she was about 11 to a man who beat her regularly. A dozen years passed. Jo Luck, the head of an aid group called Heifer International, passed through the village and told the women there that they should stand up, nurture dreams, change their lives. Inspired, Tererai ... wrote that she wanted to study abroad, and to earn a B.A., a master's and a doctorate. In 1998 she was accepted to Oklahoma State University. Heifer helped with the plane tickets, Tererai's mother sold a cow, and neighbors sold goats to help raise money. With $4,000 in cash wrapped in a stocking and tied around her waist, Tererai set off for Oklahoma. At one point the university tried to expel Tererai for falling behind on tuition payments. A university official, Ron Beer, intervened on her behalf and rallied the faculty and community behind her with donations and support. "I saw that she had enormous talent," Dr. Beer said. Tererai excelled at school, pursuing a Ph.D at Western Michigan University and writing a dissertation on AIDS prevention in Africa even as she began working for Heifer as a program evaluator.
