Whereas telling deals almost exclusively with facts,selling also involves feelings and attitudes.You donnot have to have the word"sales"in your job title to be a salesperson.In fact,everyone needs to be a persuasive communicator at one time or another.Convincing the boss that you deseve a raise or more responsibility calls for selling.So does getting approval for a new project.motivating employees to work their hardest,and convincing a supplier that you need the shipment today.It does not take much imagination to see that the success or failure of a career depends on the ability to persuade others.
