There's two ways of dealing with the rampant skepticism out there.

Either appeal to the small percentage of gullible people.

Or, in every aspect, every inch of your marketing, act to reassure and encourage your prospective buyers to overcome their well-justified skepticism.

Every. Aspect.

Every. Line.

REASSURE them. Assuage their fears.

STOKE their hopes, enthusiasms, desires, cravings, dreams.
