It turns out that we determine who our leaders are by unconscious undertones we all project with our voices - and of which we're completely unaware.

There are four different kinds of power in a communication: position power (the CEO talking to her direct reports), emotion power (passion sometimes rules the day), expertise (people often listen to the most knowledgeable person in the room), and conversational power (the subtlest, this is the ability to direct the conversation through body language).

You can strengthen your leadership voice by finding what I call its Maximum Resonance Point and learning to pitch your voice there. That gives you the strongest voice and thus the one that people are most likely to want to follow.

If you adopt the body language of a power player, it will greatly facilitate your ability to be a power player.

The world is a very big place and there are many wonderful people in with ideas you haven't thought about. Talk to them, find out what they're thinking, so that you can be the best person you can be.

You have to learn to trust - and listen to - your unconscious mind. If you pose the question to your unconscious "is this person a friend or a foe" - safe or a threat - your unconscious mind is hard-wired to assess that brilliantly for you. It's just that we're not very good at paying attention to what our unconscious minds are telling us.

We have a Marlboro Man Theory of leadership and change, especially in America, but in fact anything great that's accomplished is accomplished by many hands.
