Martha Beck is a best-selling author, life coach, and speaker and expert in coping with anxiety. Despite decades of sociology research and coaching, Beck says she'd struggled with anxiety her entire life. She says we live in a global anxiety spiral, and turned to neuroscience to understand why, and how to move past it. Through her research, Beck found that anxiety shuts down the brain's curiosity and creativity, and tapping into them can be life-changing. She opened up to Hoda about her book, "Beyond Anxiety: Curiosity, Creativity, and Finding Your Life's Purpose", and shares strategies to change the way they think and live.
