“Ads sell a great deal more than products. They sell values, images, and concepts of success and worth.”

“The difference between marketing and selling is more than semantic. Selling focuses on the needs of the seller; marketing on the needs of the buyer. Selling is preoccupied with the seller’s need to convert his product into cash; marketing with the idea of satisfying the needs of the customer by means of the product and the whole cluster of things associated with creating, delivering and finally consuming it.”

“John here," the other John said, "pioneered the concept of marketing by refusing to sell any products. It drives the market insane.”

“In a nation that has developed to a high art advertising, the creator who refuses to advertise himself is immediately suspected of having no product worth selling.”

“A firm may be defined as an institution which buys things, transforms them in some way, and then sells them with the purpose of making a profit. The things a firm buys we shall call "inputs." The things it sells we shall call "outputs." The process whereby the things it buys are transformed into the things it sells we shall call the "process of production." In any process of buying to sell again a process of production is always involved…
A business, therefore, is a process whereby certain inputs, valued in dollars in some way, are transformed into outputs, also valued in dollars in some way.”

“If a product doesn't sell, raise the price.”

“The money received for sales has no other significance or value than its power to buy, and trade can only be imaged truly as an exchange of goods for goods in which the processes of selling and of buying are complementary.”

“If a book about failures doesn't sell, is it a success?”

“Today the value of everything has increased. Men sell their sperm and women their ova for a great deal of money, but ironically, in many countries, a child can be purchased for prostitution or forced labor for a pathetic sum of 10 to 20 dollars.”
