Before walking through any door—the door to your office, a party, a meeting, even your kitchen—picture a leather bit hanging by a cable from the frame. It is swinging just an inch higher than your head. As you pass through the door, throw your head back and chomp on the imaginary dental grip that first pulls your cheeks back into a smile and then lifts you up. As you ascend high above the gasping crowd, your body is stretched into perfect alignment—head high, shoulders back, torso out of hips, feet weightless.
