The Rule of Three is a writing principle that suggests information or actions presented in threes are inherently more engaging, satisfying, and memorable than other numerical combinations. Whether it’s in the form of “Lights, Camera, Action” or “Blood, Sweat, and Tears,” sets of three have a unique way of capturing attention.
