Good advertising should give the reader essential facts about the product or company advertised and should do so engagingly without trickery or hogwash.
Leo BurnettThe most dangerous thing that can happen to us, I think, is to permit a feeling to develop that any client is a problem. I have always taken the attitude that no account is a 'problem account' but that all accounts have important problems attached to them - that you can waste more time and burn up more nervous energy by fighting a problem than by taking a positive attitude and solving it. It sure gives you a nice, warm glow when you do.
Leo BurnettI have learned that it is far easier to write a speech about good advertising than it is to write a good ad.
