I'm 2 minutes in. Lecturer revealed a formula for quality speaking. Knowledge, he says, is the biggest of the three components.
He then takes about a minute using an anecdote about Mary Lou Retton to demonstrate why knowledge is so important.
And yet, I'm wondering, how many people in his audience know enough about who she is to understand what he seems to want to say is an important point?
If they don't, then I think he just lost a bunch of them in the first two minutes.
Communication is perception and if his audience can't perceive his analogy, he hasn't communicated.
