Great speakers understand that people respond to a great challenge, even one involving huge personal sacrifice, when (1) they believe in the person making the challenge, (2) they see the challenge itself as being worthwhile, and (3) the challenge isn't sugar-coated but is put in stark, unforgettable terms. Too many public speakers mumble and drone when they would be far more effective if they said less and said it in a simple, direct way.

These are critical components. And yet all three carry enormous challenges that must be carefully managed. The people need to believe in the person making the challenge, but the speaker must not become the message. She must explain the challenge as worthwhile without pandering to their base instincts. She must challenge them - but realistically in a way that change is possible. No point calling people to action when the prospects in front of them are unrealistic.
