The Rule of Three — The presenter's oldest tool

"Life, liberty, and the pursuit of happiness." Three items is the smallest number that creates a pattern. The brain registers one as a statement, two as a comparison, and three as a pattern. Presentations, arguments, and stories land harder when they come in threes.

• Three is not a limit. It is a structure. "Tell them what you will say, say it, tell them what you said." Three steps.
• Try building your next school presentation around three points. Not two, not five. Three.
