The Life Journey of Oprah (VIDEO)

Oprah says that even as a child, she knew she would take a career path that allowed her to connect with people. Still, she never dreamed that connection would be on the scale that it is today.

"I had no idea that I would end up being who I've become," Oprah says in this video clip from "Oprah's Lifeclass". "But I had a strong belief that the calling was something greater than what Mississippi was showing me. The calling was greater than my front yard. The calling was greater than what my grandmother believed that my life could be."

Oprah also talks about the path to discovering a calling -- what it entails and where to find it.

"Lots of people think that it's about being famous or about being known or about doing big incredible things," Oprah says. "Sometimes the calling is right in your own neighborhood. Sometimes the calling is something that was just a whisper to you. When you begin to honor that whisper and to follow that, you end up being the best that you can be.

"Everybody has a calling," she continues. "And, your real job in life is to figure out as soon as possible what that is, who you were meant to be, and begin to honor that in the best way possible for yourself."
