(CNN) – Media mogul Arianna Huffington is out with a new book, "Thrive," pushing ambitious people to add a bit of balance to their lives.
"Our society has shrunken the definition down to these two metrics of money and power, which is like trying to sit on a two-legged stool, sooner or later you fall off," said Huffington, founder of "The Huffington Post."
Too often, people chasing success put their own well-being on the back burner, much to their detriment, says Huffington.
"We need to realize that we're living under a collective delusion that equates burn out with success," says Huffington.
Scientific evidence shows "that when we take care of ourselves, get enough sleep, meditate, do yoga, whatever it is that recharges us, and learn to unplug from our ever-present devices, we are going to be more effective," says Huffington.
She noted former President Bill Clinton himself said the most important mistakes he made in his life were when he was tired. Hillary Clinton, says Huffington, should do it differently.
Referring to the title of the former Secretary of State's new book, Huffington said, "I'm hoping that "Hard Choices" will mean her making some hard choices about how she prioritizes her own self, too, and how she deals with stress."
"She could be an amazing role model of someone – if she decides to run even – who'd run a presidential campaign without completely burning out as most of them do, and show there are other ways to do it," said Huffington.
