Arianna Huffington believes she can give you a better life. Though her point of view has shifted countless times over the decades, what's never changed is her fierce advocacy for issues she cares about—which are many times political, but just as often personal.
Her first taste of fame came at 23 when, as a member of the University of Cambridge's debate team, she published a book attacking women's liberation. Two biographies followed, of Maria Callas and Pablo Picasso, before Huffington moved to the U.S. and became a right-wing advocate. In the late '90s, her politics took a dramatic left turn, which led to the idea for her eponymous site.
