The English philosopher Bertrand Russell, in The Impact of Science on Society, states simply, "If you feel love, you have a motive for existence, a reason for action."
People want to fall in love. A good salesman should let them.
To explain what I mean by this, let me step backwards for a moment. The root of quality selling must always be in having something valid, something true, something genuinely helpful to sell. If you don't have this, don't even begin to try to sell. If you try to sell that in which you have no passionate belief or something that is false you are dead. You are a servant of the devil. You are an apostle of the unsavory. You are Bernie Madoff. You are a fraud and incipient thief, as well as a killer of your own soul.
Perhaps this is obvious, but, in truth, good selling begins with a moral choice to purvey a real value and it is essential to know this in advance.
But assuming the real value of your selling proposition, salesmanship is really nothing more than helping people be selfish, helping people do the right thing for themselves. Some of this is listening truly and intently, some of this is sincerely caring about who you are conversing with.
The salesman's job is to guide people to "fall in love" with that which can raise them up. The salesman's job is to help a business client succumb to that which, in varying degrees, offers ROI salvation for himself and his firm.
It cannot be denied that most of us associate falling in love with erotic desire. Indeed, like a new lover, a salesman's job is to make the truth sexy. A passionately told truth is and should be a heart-fluttering aphrodisiac.
Dr. M. Scott Peck, in his profoundly insightful book The Road Less Traveled talks extensively about the nature of love. He states, "...falling in love is a trick that our genes pull on our otherwise perceptive mind to hoodwink or trap us into marriage." But, for Peck, falling in love is also a tool for initially breaking down barriers separating us all from a deeper love, a deeper truth and an agapic potentiality. Theologian Paul Tillich said, "The first duty of love is to listen."
A good salesman, like a good lover, combines a conscious employment of qualities like looks, charm, wardrobe, and, most importantly, a well-honed charisma of expressed faith in a product. Charisma emanates from a fervid inner truth and an embedded belief. A focused salesman leaves a palpable frisson in his wake and should awake an ardent longing in a potential client to do what is in the client's best interest anyway. Effective salesmen are evangelists of "the good."
