Since ending her TV chat show after 25 years, Oprah Winfrey has decided that she wants to become a school teacher and will be taking a class called 'It's Life 101' at her school in South Africa later this year.

Winfrey, who is heading up her OWN network, recently went to South Africa to visit her "girls", who have now become her life.

In an email to her fans, Oprah wrote: "They were all stressed for tests, but doing fine. No major crisis this trip. I love being with them and talking to them about all things important. When I'm there I'm talking from the time I get up till I go to bed, about EVERYTHING teenage girls are going through. It's the same all over the world."

The media mogul has decided to return to the country this autumn and teach a class.

"Should be fun since I love to teach. And they're like sponges," Oprah explained. "Like 12th graders everywhere, this first class is both anxious and excited about going to college. Most will be the first in their family. So it's a very big deal for them, and they're feeling the pressure."

Winfrey has been moved by the struggle that many young people face and is determined to help, and her trip overseas has helped her appreciate the U.S. more.

"When Chris Rock was last on the show he said, 'real wealth is having options.' I thought that was pretty profound," Oprah wrote. "I now stress to my girls that education prepares you to have options. Without it you have none. Just took a walk around the neighborhood watching sprinklers on the back lawn ... (I love sprinklers) Made me think about the red dirt road I traveled from Mississippi (no sprinklers) to the here and now ... And how that journey could have only been possible in the USA."
