Advertising

Bill (William) Bernbach - one of the three founders of Doyle Dane Bernbach (DDB)
"Logic and over-analysis can immobilize and sterilize an idea. It's like love -- the more you analyze it, the faster it disappears."

"Nobody counts the number of ads you run;they just remember the impression you make."
"The truth isn't the truth until people believe you, and they can't believe you if they don't know what you're saying, and they can't know what you're saying if they don't listen to you, and they won't listen to you if you're not interesting, and you won't be interesting unless you say things imaginatively, originally, freshly." 

"Good advertising builds sales. Great advertising builds factories."
