From A Weak to Confident Communicator - 30 Day Challenge

When you speak, you only hear yourself. You have no clue how your body language is. Your gestures and posture form a crucial part of your communication. If you have ever recorded a video of your speech, you know how you did.
But you cannot always record a video of every conversation. An alternative is to use mirror practice instead
Today, you will practice in front of a mirror. You can attempt to give a speech, a presentation or assume you are talking to an invisible person. When you watch yourself talk, you will understand where you go wrong. Once you gain awareness of your mistakes, correcting them becomes easy.
