Paloma Cristina Terra, 19, has a 6-month-old daughter named Maria Victoria and lives in a slum neighborhood in Rio de Janeiro, Brazil. She dropped out of school in sixth grade and has never held a job. Her prospects would be bleak, except that she and her best friend have enrolled in Projeto Mao na Massa, or The Hands On Project, which trains and certifies women in construction jobs.
