I was doing a campaign once for a manufacturer, and I couldn't think of an ideas, and I was kind of desperate about it. The night before I had to show something to my client I had a dream, an interesting dream. I woke up and for once in my life I wrote it down and went back to sleep Next morning I went to the office and had that dream out into a TV commercial which is still running thirty years after and which has made that particular product the leader in its field.
