Gail Sheffler originally shared this TED talk with me and I believe that it is worthy to share to all.
How are you sitting in the meeting you are in right now? How do you prepare for a presentation? Do you feel confident?
Amy Cuddy (2nd talk on the page, scroll a bit down) shows us how to "Fake it until you beome it". Simple poses you can do for 2 minutes that help your body change your mind. Enjoy!
