The whole reason to study (and learn to control) body language is to have that support (rather than undercut) your message.

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.

Every human emits unconscious vocal undertones that determine who the leader is in the room.

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

Being embarrassed means that you're human, and we like you better for it

The person in power takes up the most space.

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.
