The Tribe On Being A Working Woman (VIDEO)

Are you a working mom who sometimes feels guilty about neglecting either your kids or your job? In this exclusive Becoming Fearless video, Arianna Huffington and three high-profile celebs and authors share some of the working-mom lessons they've learned over the years. As Arianna says, "More and more women are working to makes ends meet. But that's where the guilt comes in. Sometimes I feel that when they take the baby out, they put the guilt in."

From actress and director Christine Lahti to authors Jane Buckingham and Christine Hassler, these all-star experts have mastered the art of being fearless in their careers while maintaining family connections. "We're all flawed, and we're all doing the best we can," notes Lahti.

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, Sherri Shepherd, E! News anchor Giuliana Rancic -- as they examine fearlessness and its impact on love, money, parenting, work, health and beauty.
