The relationship between a manufacturer and his advertising agency is almost as intimate as the relationship between a patient and his doctor. Make sure that you can life happily with your prospective client before you accept his account.
We are all advertising, all of the time. If you want to sell your car, what do you do? You clean and polish it and make it the best you can. Some people bake bread when they are trying to sell their house because the smell adds a friendly feeling. Even the priest, with all his or her fervour, is advertising God. Everybody is selling.
