WATCH: Simple Sleep Tips With Dr. Breus

Do you feel like you never quite get enough rest? In this exclusive Becoming Fearless video, Arianna Huffington and "sleep doctor" Michael Breus, Ph.D., share some easy things you can do to sleep better, live better -- and be more fearless. "You can actually make sure that you get enough sleep," notes Dr. Breus.

"We are living in this world where we still believe that, in order to succeed, somehow we have to work 24/7 and be always hyper-connected," says Arianna. Put the tips from this video into action, and you too can (as Arianna puts it) "literally sleep your way to the top"!

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, Dr. Phil -- as they examine fearlessness and its impact on love, money, parenting, work, health and beauty.
