How Sheryl Sandberg Learned She Couldn't Do More On Less Sleep (VIDEO)

For years, Sheryl Sandberg thought the key to getting more done was getting by on less sleep, she said on a recent appearance on HuffPost Live.

Since this realization, she's been aiming to get seven to eight hours each night, she said, a big improvement over the four to five she used to squeeze by with.

Watch the clip above for more on how she prioritizes smart choices that help her and her family thrive.
