"I'm so grateful," she tells PEOPLE of the 2007 collapse that pushed her to change her priorities
One minute, Arianna Huffington was calling her office in New York and checking emails, and the next she was lying on the floor of her Brentwood home in a pool of blood.
When she awoke, her daughter Christina, then 17, was cradling her head in her lap, her cheekbone was broken and her eyelid was cut from a fall.
“I had no idea what had happened,” recalls the editor-in-chief of the Huffington Post. Adds Christina, “It was terrifying.”
Even scarier? Huffington had no idea what was wrong with her; she spent weeks undergoing tests. As it turned out, the answer was simple: She was exhausted from working 18-hour days, seven days a week while expanding the Huffington Post, which she co-founded, into the hugely successful news site it is today.
Looking back now at her 2007 collapse, Huffington tells PEOPLE, “I’m so grateful for this wake-up call that changed my life.”
Now the 63-year-old reformed workaholic – who still maintains a packed schedule but tries to get seven to eight hours of sleep each night – is urging others to realize that rest is part of success, in a new bestselling book called Thrive: The Third Metric to Redefining Success and Creating a Life of Well-Being, Wisdom and Wonder.
