At drive virksomhed uden, at reklamere,
er som at vinke til en pige i mørket.
Du ved hvad du laver, men igen andre ved det.

Citat af Steuart Henderson Britt (1907-1979) Ph.d. i psykologi fra Yale University.

Originalt: Doing business without advertising is like winking at a girl in the dark.
You know what you are doing, but nobody else does.
