Joseph Grenny, New York Times bestselling author and behavior change expert, tells the story of Jane, a woman born in the Mathare Slum in Nairobi, Kenya. As a child, Jane was sexually molested by her father, had her first baby at age 13, is now a mother of four, worked as a prostitute to support her family on 50 cents a day, and is HIV positive. The world couldn't be more bleak for Jane and the tens of thousands of young African girls with her same story. But, Jane completely changed her life. By changing her behavior, she left the slum, moved into a house, and brought herself out of extreme poverty and prostitution.

Joseph walks you through Jane's inspiring transformation while identifying the remarkably simple science of behavior change she implemented along the way. With just a few simple principles founded in decades of the best social science, we can literally change the world by changing behavior.

In the spirit of ideas worth spreading, TEDx is a program of local, selforganized events that bring people together to share a TEDlike experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, selforganized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are selforganized.*
