Tony Robbins: Align Your Mind & Body
"If you say, 'I absolutely will do that,' and your physiology is unified -- that is, your posture, your facial expression, your breathing pattern, the quality of your gestures and movements, and your words and tonality match -- you absolutely will do it. Congruent states are what we all want to move toward, and the biggest step you can take is to be sure you're in a firm, decisive, congruent physiology. If your words and your body don't match up, you' re not going to be totally effective."
