African American Socialite Oprah Winfrey open up to her secret of maximum concentration and she holds it to the fact that she doesn't watch TV or radio that much.
The media mogul may have her own network, OWN, but she doesn't watch programmes or listen to the radio at home because she finds background noise affects her "energy".
She said: "Nothing keeps me awake at night. I don't watch news before bed. I have a very sensitive spirit - I absorb other people's feelings and empathise with them.
"I have to measure the energy that comes from my private space. I'm never in the house with noise - other than dogs yapping. I don't leave the TV or radio on. I don't have energy coming into my sphere that I'm not consciously inviting in."
