Oprah Winfrey says running a TV network is 10 times harder than presenting her talk show. The media mogul - who quit 'The Oprah Winfrey Show after 25 years to launch her own network OWN - admitted after a week in the job she is finding it difficult to adjust and often needs to stop to catch a breath. Writing on her Facebook page, Oprah said: I will say this; its 10 times harder than doing my daily show. Doing that show felt like breathing every day. Now Im in so many meetings I sometimes have to step out and catch a breath. However, Oprah is relishing the challenge and says she is not worried about the future of the channel. She said: @Woodsy1069 asked me on Twitter yesterday if I was frazzled by OWNs performance thus far. Nope, not frazzled. And I have faith that if I do what Im supposed to-allow it to serve my purpose, and you, the viewer - it will succeed. EPS
