I warn you against believing that advertising is a science.

Logic and over-analysis can immobilise and sterilize an idea. It's like love. The more you analyse it, the more it disappears.

Never do anything yourself that you can hire someone else to do, especially if they can do it better.

Don't confuse good taste with the absence of taste.

The heart of creativity is discipline.

You cannot sell a man who isn't listening; word of mouth is the best medium of all; and dullness won't sell your product, but neither will irrelevant brilliance.

You have to live with your product, you have to know it through and through, you have to look at it, understand it, love it then, and only then, you can crystallize in one clear thought, one single theme, what must be conveyed about the product to the consumer.
