I stumbled over this TED talk a while back and while there are a a lot of great talks out there I just don't have the time to listen to many of them. But once in a while I click on the play-button and sometimes it's a really worth while-listen. For felines and humans alike.
This one is with social psychologist Amy Cuddy and how we can 'fake it 'til we become it' by using the right body language. And it's not faking your knowledge or skills but about how you can boost your confidence and even success rate by power posing. Which can apparently affect the testosterone and cortisol levels in your brain.
It's an interesting and multi-layered talk that makes you think. And learn.
