It's much easier to be convincing if you care about your topic. Figure out what's important to you about your message and speak from the heart.

Most people would rather jump through rings of fire than give a speech.

Just as with swimming or riding a bike, you can't really learn how to fall in love from reading a book not even this one. Sure you can read about the different swimming strokes or the parts of a bicycle; you can learn the theory and physics behind the sport. But to get to the heart of the matter you've got to leap in and learn by doing.

When speaking, be clear, be brief and be memorable.

If there's anything a public servant hates to do it's something for the public.

The stroke of the whip maketh marks in the flesh: but the stroke of the tongue breaketh the bones. Many have fallen by the edge of the sword: but not so many as have fallen by the tongue. [Ecclesiasticus 28:17 --18].
