At least one-third of the people we know are introverts. They are the ones who prefer listening to speaking; who innovate and create but dislike self-promotion; who favor working on their own over working in teams. It is to introverts—Rosa Parks, Chopin, Dr. Seuss, Steve Wozniak—that we owe many of the great contributions to society.

Up to 40% of people consider themselves shy. You might say you're introverted or awkward, or that you're fine around friends but just can't speak up in a meeting or at a party. Maybe you're usually confident but have recently moved or started a new job, only to feel isolated and unsure. If you get nervous in social situations - meeting your partner's friends, public speaking, standing awkwardly in the elevator with your boss - you've probably been told, "Just be yourself!"

It's the hidden epidemic of small moments of anxiety that infiltrate both our work and personal lives. Because each individual microstress is so small, it doesn't trigger the normal stress response in our brains to help us deal with it.

The good news is that once you learn about microstress, you can fight back.
