WATCH: Becoming Fearless About Work (VIDEO)

How fearless are you when it comes to your career? In this exclusive Becoming Fearless video, Arianna Huffington and familiar faces such as E! News anchor Giuliana Rancic, comedian Kathy Griffin and "The View" cohost Sherri Shepherd share some of their hard-earned wisdom about work. "Work is a fundamental part of how we express ourselves in the world," notes Arianna. "It provides identity, purpose and, if we’re lucky, meaning. Fearlessness gives us perspective on the role of work in our lives."

"The biggest reward you can get from being fearless at work is when it actually pays off," says Kathy Griffin. "That means you’re making somebody else happy. In my case, you’re making somebody else laugh."

Says Giuliana Rancic, "You could ask me to do anything at work. From coffee to Xeroxing to cleaning your desk out to vacuuming…. I would do anything. And people took notice of me as a hard worker."

The 10-part Becoming Fearless video series is sponsored by Toyota Corolla and will run through August. Hosted by Arianna Huffington and inspired by her book "On Becoming Fearless," the series will explore how fear affects our lives -- while celebrating the strength, courage and resilience that result from overcoming it (or at least trying to).

During the course of the series, Arianna will be joined by noted individuals -- Martha Stewart, Corcoran Group founder Barbara Corcoran, Jenny Craig CEO Dana Fiser -- as they examine fearlessness and its impact on love, money, parenting, work, health and beauty.
