Most powerful person in a room is the one who knows how to be aware consciously of themselves and those and around AND knows how to influence the moment with body language, words, looks, listening skills and NLP tricks.
For good or for bad, you are either being influenced or you are the influencer in any given moment. Which would you chose to be?
We are watching a political world where the most influential leaders are not the benevolent and reasonable but the most hypnogogic. That is the fact of life. So consider your role in life, at work, at home, in your country, in your mind.
