♦ First, adopt the body language of someone who’s utterly depressed. Let your shoulders slump, your head hang, your face sag. Now, without moving a muscle, try to feel really, truly excited. Go ahead, try to see if you can create any excitement without moving. It’s nearly impossible. ♦ Now do the opposite. Physically spring into excitement. Jump up and down as if you’ve won the lottery, smile the biggest smile you can, wave your arms in the air, and while doing all this, try to feel depressed. Again, it’s nearly impossible. Here are a few more physiological changes to play with: ♦ For confidence, assertiveness, and to be able to emanate gravitas, imagine playing the role of a military general—take a wide stance, puff up your chest, broaden your shoulders, stand straight, and confidently put your arms behind your back. Feel the effect of this posture internally. ♦ For a boost in both energy and warmth, stand up, stretch your hands as high up as possible, inhale as much as you can—imagine your rib cage expanding, doubling in size—make the biggest smile you can and look upward, hold for a second, and then relax everything.
