1. After you tell me what you're going to talk about, tell me why I should be listening to _you_. Why are you an authority on this topic? Unless you're famous, I don't know you.
2. The talk should contain 50% or less of your knowledge on the topic. You want to keep some info "in your back pocket" to ad lib with.
