The Psychology of Salesmanship. Atkinson William Walker

authority gives the following directions for the correct position in standing: "(1) Heels together; (2) head up, with chin slightly drawn in rather than protruding; (3) eyes front; (4) shoulders thrown back but not elevated; (5) chest expanded; (6) abdomen slightly drawn in, and not allowed to protrude; (7) arms dropped naturally to the sides, with the little fingers lightly touching the sides of the thigh. This may make you feel a little stiff and awkward at first, but, if you persevere, will soon establish itself as second nature with you."

      Another authority says: "The easiest way in which to acquire a correct carriage is to imagine that you are suspended from on high with a line, the lowest end of the line being fastened to the lower end of your breast-bone. If you will stand and walk as if you are so suspended, the result will be that you will acquire an easy, graceful, gliding walk, and a correct carriage and natural position." Another authority gives the following advice: "The following method if observed in walking and standing, will impart a desirable physical poise and will keep you erect and in a graceful attitude while walking: Stand with your back toward the wall, with the heels, legs, hips, shoulders and back of head touching the wall, and with the chin slightly drawn in. Press up against the wall firmly. You will find yourself in an uncomfortable position, and one that is unnatural and incorrect. Then, keeping your heels to the wall, allow your body to swing forward into a natural position, being careful to keep the body firm in the same 'form,' avoiding relaxation, swinging yourself forward from the ankle joints alone. When you find that the correct poised, natural position has been attained, hold it, and march forward in what will be the natural, normal, well-balanced walking position. Practice this repeatedly, several times every day, until you have fully acquired the habit."

      Shaking Hands. When you grasp another's hand in the act of "shaking hands," do not do so in a listless, cold-blooded manner – do not extend to the other man a flabby, clammy, fish-like hand. But take hold of his hand as if you liked to do it – throw interest into the proceeding. More than this – throw feeling into it. Throw into the hand-clasp the feeling: "I like you, and you like me." Then, when you draw your hand away, if possible let your fingers slide over the palm of his hand in a caressing manner, allowing his first finger to pass between your thumb and forefinger, close up in the crotch of the thumb. Practice this well, until you can perform it without thinking of it. You will find merit in the method. Grasp the other person's hand "as if he were your best girl's millionaire father-in-law."

      Voice. The Salesman should cultivate a voice with expression in it. His voice should convey his belief in what he is saying, and his interest in the story. You will find it an aid in this direction if you will learn to visualize your thoughts – that is, to make a mental picture of the thing you are saying. One can always describe better that which they see before them. In the degree that you can see your mental picture, so will be your degree of power in expressing it to another in words, and so will be the degree of feeling in your tone. The voice should express the meaning of your thought rather than being merely the symbol of it. Try to say "Good Morning" as if you meant it – then say it in the usual way. Do you see the difference? Throw your thought and feeling into your voice. Forget all about yourself and the other man and concentrate your thought and feeling into your voice.

      Many people make the mistake of "speaking with their muscles instead of with their nerves." They throw muscular energy into their words, when they should use nervous energy, or thought-force. The former has but little effect on the mind of the other, while the second vibrates subtly and reaches the feelings of those addressed. Feel, when you wish to speak impressively, and your tones will reflect the same, and induce a similar feeling in others. It is a point worth remembering that one may "bring down" the voice of an excited person to one's own pitch, if the latter is firmly held at the customary pitch, in a firm manner. Not only does this "bring down" the other man's voice, but his feelings will also follow suit, and besides, you also manage to keep your own temper and poise. Never raise your voice because another raises his – resist the tendency, and maintain your poise and power by so doing. This is worth remembering.

      The Eyes. Learn to look people in the eyes when you are speaking to them. Not in a staring manner, but firmly, politely and easily. This may be acquired with a little practice. Practice on yourself in the mirror if you prefer. A shifting, restless gaze produces a bad impression, while a firm, honest gaze will incline people in your favor. You will find that strong men – men who influence others – almost always have a firm, strong gaze. It is worth practice, work and time, to acquire this personal trait.
