Body language as a training tool?

We are fans of Ted videos. One of the recent one we saw was about body language used to train and develop ourselves. We all know that body language affects how others see us, but it may also change our self-image.

The presentation by social psychologist Amy Cuddy posits that “power posing” — namely, adopting a confident posture, even when we shake in our boots — might affect testosterone and cortisol levels in the brain, and as a result might influence important personal outcomes. I bought the argument and strongly suggest you watch that video too!
