I want to share with you a talk given by a social scientist on TED talks:
if you can watch an MP4 with your computer, it's a pretty short presentation but very moving and useful and I wonder how the information here relates to the poses we use in Awakening Stillness Qigong, I suspect there is at least a correlation.
If you cannot get the talk to download so that you can see the poses, it is basically about taking a power pose in private to increase your dominance hormone (testosterone) and lower your stress hormone (cortisol) take one of these confident postures for two minutes in private, regularly, and watch your confidence and comfort levels rise. Try it! Stand like Wonder Woman with your hands on your hips or raise your arms in a victory salute like a runner at the finish line, and smile. That's all, the body reacts like those things happened for real and you benefit, lasting changes can happen. So fake it til you become it.
