A must watch TED Talk by Kelly McGonigal on how the simple belief that stress is bad for you can actually make stress bad for you! The take-away: you have the power to change how you think about stress, and how your body reacts to it.
“Harmful effects of stress on your health are not inevitable. How you think and how you act can transform your experience of stress. When you choose to view your stress response as helpful, you create the biology of courage. And when you choose to connect with others under stress, you can create resilience.”
