Engage and Distill

Rhetorical questions might seem overused, but charismatic leaders use them all the time to encourage engagement. Questions can have an obvious answer or pose a puzzle to be answered later.

Three-part lists are another old trick of effective persuasion because they distill any message into key takeaways. Why three? Because most people can remember three things; three is sufficient to provide proof of a pattern, and three gives an impression of completeness.
