Huffington, Sandberg Say Getting Enough Sleep Is Key to Success

One of the most important keys to success, according to both Sheryl Sandberg and Arianna Huffington, is getting enough sleep

The two women appeared onstage at Davies Symphony Hall in San Francisco Thursday to discuss the importance of being well-rested, gender equality in corporate America and the need to change the definition of success — the theme of Huffington's latest book, Thrive.

During the sold-out event, sponsored by the Commonwealth Club of San Francisco, Sandberg and Huffington offered insights into what it means to be successful, and why people need to spend more time relaxing.
