    This is one of my favourite Tedtalks ever! These power poses really do allow you to harvest your best self in any stressful situation.. at times when I feel powerless I definitely need to go back and try this technique. Amy Cuddy did an amazing talk, even after watching this you feel just a little more powerful.
