Informing them is a necessary evil. It is the part you don't want to do, but you must. It makes them work. People have to work to be informed, and I would much rather carry them along in an effortless experience.

Each paragraph is a sentence. The first sentence of the paragraph IS the paragraph. The rest of the paragraph explains the idea.
So... a speech with 5 paragraphs has one main idea that you repeat at the beginning and end... and it has 3 sub-ideas.
