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 all need to be astute in sending and reading power cues, so that we can prevent ourselves - and the world - from being manipulated by evil geniuses like Hitler.

Use your unconscious mind to read other people's intents, emotions, and desires.

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.

The key is to become aware of how you are signaling your presence in meetings, conversations, speeches - everywhere you show up. Then you can take charge of them.

Sometimes, with leaders, the stakes are very high indeed. Churchill, in WWII, for example, could not afford to utter publicly his concerns about England's ability to survive Hitler's onslaught. He thought about them, but the leadership conversation sometimes needs to inspire, not voice doubt.

You have to begin by posing questions to your unconscious mind, and then listening very carefully for the answers. If you pose the right kinds of questions, and listen well, you can begin to tap into the power of your unconscious mind.
