Awareness is not just what you see going on around you. It is also about what you communicate to the world through your body language and also your own inner dialogue.
Your inner dialogue is shaped by the thoughts we think. The thoughts we think about ourselves matter. Your self worth and how you see yourself influence the experiences you have in your life. The signal you transmit to others is based on your predominant thoughts. If you think you are weak, or you are not confident then you are broadcasting this to the world around you.
Most importantly this includes people who may take advantage of that weakness or lack of confidence.
