The power poses that Amy Cuddy teaches can translate into winning more negotiations and building better relationships. Or they could backfire and cost you money and friends. Your success depends on how well you master external and internal mindfulness.
Power poses may make you feel confident and relaxed. Blood tests even show they boost testosterone and reduce the stress hormone cortisol. But other people might read you, instead, as arrogant, entitled, or just clueless. Suppose you get an email with a job offer. You might strike a power pose, and confidently call them back with your “salary requirements.”
