How did your last conversation with your spouse/parent/kid/etc go? Still blaming them for it? Did you know that what you say will influence human behavior only 7% of the time? How you use your voice (quality) is much more important and is 38% of what influences another person. But 55% of the conversation comes from your physiology - how you use your body. Think a moment about that conversation that went sour. Is the other party still to blame? Did you play a part in that? How can you fix it? Better yet - do you want to?
