Mind & Body Language Control
If you are in control of your mind, or someone else’s mind, the body will respond in ways that are consistent with the emotions it is presented with.
When you are in a negative mood, for example, you will have a tendency to stare at the ground, avoid eye contact, and slouch.
Knowing how to control your own body language is an invaluable skill. If you use dominant body language, you will feel more dominant. If you use submissive body language, you will feel more submissive. Because your emotional and logical brains don’t work well together, you can control your body during times when you are too emotional to control your mind and, conversely, you can usually control your mind if you find that you can’t control your body. You must learn to manage both independently of each other so that when one goes haywire, you can use the other to prevent yourself from screwing up social situations.
