"I was taught to read at an early age. By the time I was three, I was reciting speeches in the church. They'd put me up on the program, and say, 'Little Mistress Winfrey will render a recitation,' and I would do 'Jesus rose on Easter Day, Hallelujah, Hallelujah, all the angels did proclaim.'"

Oprah Winfrey's public speaking career began in 1957. At three, she was speaking in church, by her teens she was touring the churches of Nashville, reciting the sermons of James Weldon Johnson. Other children sang, Oprah talked. And she's still talking -- but to much larger audiences. The path that led from her grandmother's farm in Kosciusko, Mississippi to becoming the first African-American woman billionaire is a story of unwavering focus and unrelenting determination.
