What kind of a man should the salesman be, in order to be successful?
The essential qualifications are, good health, good appearance, a
thorough knowledge of what he offers for sale, and a general
knowledge of his competitors' goods. Furthermore, he must know how
to judge a customer, so as to present his thoughts in a manner to
gain his confidence. He should also develop his sense of humor, in
order to overcome the "hard knocks" that may be in store for him. He
must be able to smile, no matter what happens. If he possesses these
qualifications, together with the proper goods to sell, plus the
capacity for _work, work, work,_ then he will assuredly make a
successful salesman.
