Is stress your enemy? In her fascinating TED talk, psychologist Kelly McGonigal presents new research that poses that it's all a matter of perspective; stress is only bad for you if you think it is. And she offers advice on how to change your mind about stress in order to change your body’s response to it.

"Chasing meaning in your life is more important for your health than avoiding discomfort. Go after what you want and trust yourself to handle the stress that follows." - Kelly McGonigal
