Power pose, dammit
This is just a reminder that your body language controls the way you feel, which often determines how you act. To feel powerful, adopt powerful body language and hold it for a while.
Wait, you say, wasn’t power posing totally debunked? No. But more importantly than what scientists say, why not just try it? What will it cost? Do two minutes a day for two weeks. Anytime you notice your body language when nobody is watching, just try to make it more expansive. If you don’t feel any different, go ahead and stop. But I bet it will make a difference.
Science shouldn’t take a back seat to personal experience. But I would also say that that your personal experience is science.
