Miller opens with the book's foundational principle: if you confuse, you lose. Customers won't spend energy deciphering an unclear message, no matter how good the underlying product is — so the top priority of any marketing is radical clarity, not cleverness.

Why this matters more than most marketers assume:

• The human brain is wired to conserve energy, and confusing marketing copy simply gets ignored rather than puzzled over
• Miller argues most company websites and marketing fail this test by trying to communicate everything about the company at once, rather than one clear, simple message
• This principle sets up the rest of the book's framework, which exists specifically to force this kind of clarity through a repeatable structure

This opening reframes marketing's core job as clarification, not persuasion through complexity or cleverness.
