Positive body language, including smiles, eye contact, a pleasant tone of voice and persuasive gestures, has a proven impact on the success of presentations. On the other hand, negative non-verbal communication, including averting eyes, frowning face, nervous movements or stiff body posture, can ruin the whole performance.
For example, politicians who have special advisers focused on non-verbal communication know this very well. Do you know how good you are in communicating non-verbally?
If you want to find out, there is nothing simpler than to let yourself be recorded during your presentations or other public appearances. Then analyze what gestures you use, how your face looks, how you stand, where you look, and so on.
