Arianna appeared on ABC's 'This Week' to discuss Hillary Clinton's potential 2016 presidential run

"She's obviously running but what I was hoping is that she would have taken more time to become what she called herself untired," she said. "She wanted to sleep in, to be able to recharge herself. She hasn't given herself that time. I think that is sending a bad message to women, that the only way to succeed is to drive yourself into the ground."

Arianna urged Clinton to set a better example for work-life balance.

"She could be an incredible leader in helping us do our life and our success differently," she said.
