Amy Cuddy gave a fascinating, and research-backed, suggestion for anyone heading into a job interview, a first date or a public speaking event: stand in front of a mirror, put your hands on your hips, tilt your chin up, and make yourself as tall as you can get. Even better: throw your arms up and out. In her lab, Cuddy found that “power posing” for two minutes was enough to increase testosterone levels and decrease cortisol, making people feel more in control.
