This is the art of selling.
Every business person, whether on a dusty street in the Middle East
or in an air-conditioned high-rise in New York City, has to convince
the buyer that his product is the best and that the buyer would be
missing out on a great deal by walking away from the transaction.
The object of the person or company selling the goods and services
is to convince the buyer that he will get more than he is being asked
to give.
