Prince William: I dream of Africa

Dreaming of Africa is one way that Prince William escapes from the stresses he faces as the future king of Britain.

"I regularly daydream," The Duke of Cambridge reveals in the documentary "Prince William's Passion: New Hope, New Father."

"Africa is definitely one of the places I go to ... I have hundreds of animals on my iPhone. So if I am ever having quite a stressful day ... you can put a buffalo on in the background or a cricket,"

he says.

This may sound like a small, even trivial, detail but it's a thought that may one day help define the British monarchy. "It takes you back instantly to the (African) bush. And it does completely settle me down."

Prince William will one day be king, and he's acutely aware of the responsibility that comes with that; it weighs heavily on his thoughts. And even before he takes on that mantle, he's grappling with the often unwelcome attentions of the world media.
