A language like Ruby is a toolbox with some really neat little tools that do their job really nicely. JavaScript is a leather sheath with a really really sharp knife inside. That knife can cut anything, and with it you can do anything. You can kill a bear. You can catch fish. You can whittle a piece of wood into a pony. It's even a toothpick.

The conscious mind is easily overwhelmed. The unconscious mind is vast and far more powerful, but by definition we're not aware of it.

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).

Leaders can only lead willing, preferably zealous followers so don't get too far out in front of your team.

CEOs will struggle to keep themselves and their companies current, relevant, and ahead of the curve.

Mirror neurons make human empathy possible.

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.
