Body language affects how others see us, but it may also change how we see ourselves. In this TED Talk social psychologist Amy Cuddy shows how “power posing” can affect testosterone and cortisol levels in the brain, and might even have an impact on our chances for success. Amy Cuddy’s research on body language reveals that we can change other people’s perceptions — and even our own body chemistry — simply by changing body positions.

Watch it until the very end. It’s powerful.
