An old French mathematician said: “A mathematical theory is not to be considered complete until you have made it so clear that you can explain it to the first man whom you meet on the street.”
Your key message, your unique product or service, your key point of difference should resonate with everyone.
(And surely your message isn’t as complex as a French mathematical theory.)
Boil it down until everyone understands it. Unless everyone can understand it, few people will.
Here are some quick ways to test this out.
Explain it to your dentist.
Explain it to your barista.
Explain it to your parents.
Explain it in 140 characters or less.
