Don't expect your agency to pay for all the dry holes they drill on your behalf. - David Ogilvy

I had a friend who was the king's surgeon in England. One day I asked him what makes a great surgeon. He replied, "What distinguishes a great surgeon is his knowledge. He knows more than other surgeons. During an operation he finds something which he wasn't expecting, recognizes it and knows what to do about it." It's the same thing with advertising people. The good ones know more. How do you get to know more? By reading books about advertising. By picking the brains of people who know more than you do. From the Magic Lanterns. And from experience. I can't stand callow amateurs who aren't sufficiently interested in the craft of advertising to assume the posture of students.

The hallmarks of a potentially successful copywriter include: Obsessive curiosity about products, people and advertising. A sense of humor. A habit of hard work. The ability to write interesting prose for printed media, and natural dialogue for television. The ability to think visually. Television commercials depend more on pictures than words. The ambition to write better campaigns than anyone has ever written before.

Sales are a function of product-value and advertising. Promotions cannot produce more than a temporary kink in the sales curve.
