Triple Impact Method

There is a reason great speakers group things in threes. "Life, liberty, and the pursuit of happiness." "Friends, Romans, countrymen." Three is the minimum pattern the brain recognizes. Two feels incomplete. Four feels excessive. Three feels just right.

Use the rule of three at every level: three main points in a speech, three examples in an argument, three adjectives in a description. "This approach is faster, simpler, and cheaper."
