Keeping one's intensity in check is tough. Its hard not to come across as cold and aloof as a result of keeping it at the the lowest setting. Patience and empathy go a LONG way to see how one is being perceived.

One has to tailor the subjects, the simultaneity, complexity, words and emotions to the audience and the situation. Too much information, too many ideas, too many tracks, and too much to much overwhelms people and makes them shut down or just run away screaming!
