Kelly McGonigal: Stress

“Stress is what arises when something you care about is at stake. This definition is big enough to hold both the frustration over traffic and the grief over a loss. It includes your thoughts, emotions, and physical reactions when you’re feeling stressed, as well as how you choose to cope with situations you’d describe as stressful. This definition also highlights an important truth about stress: Stress and meaning are inextricably linked. You don’t stress out about things you don’t care about, and you can’t create a meaningful life without experiencing some stress.”
