It's hard to believe things sometimes don't work for Oprah.

The invitation from Harvard University caught Oprah Winfrey at a low point. Her new TV network was struggling, branded a flop in the media, when Harvard President Drew Gilpin Faust called last year to ask Winfrey to address 2013 graduates.

The request came "in the very moment when I had stopped succeeding," Winfrey recalled.

She headed for a long shower to think ("It was either that or a bag of Oreos," she joked) and emerged resolved to change her story by the time her speech rolled around.

"I want you to remember this: There is no such thing as failure," she said. "Failure is just life trying to move us in another direction."

Winfrey spoke during the afternoon session of Harvard's 362nd commencement before a packed Harvard Yard. The media mogul and former talk-show host urged graduates to find their own story, which she described as their true calling or purpose.

"When you inevitably struggle and find yourself stuck in a hole, that is the story that will get you out," she said.

Her own calling, she said, was to use television to show people "that what unites us is ultimately far more redeeming and compelling than anything that separates (us)."

In Oprah's world stumbles are inevitable but not permanent.

In Harvard's world, too.

I hope that's true for my world as well.
