ITH THE SELLING PROCESS covers in outline the whole
subject of Salesmanship. But the scope of this set does not afford room
to give here a minutely detailed exposition of the special processes of
making sales in particular businesses. I have compiled for you, rather,
the _general principles_ of effective selling that may be _universally
applied_. "Certain Success" and "The Selling Process" are handbooks of
fundamental ideas which each reader, by his individual thinking, should
amplify and fit to his own work or ambition.

[Sidenote: Real Study Required]

The fine art of successful salesmanship cannot be mastered in a few
hours of casual reading. You will not be able, immediately after
glancing through these books, to unlock every long-desired golden
opportunity with absolute assurance. CERTAIN SUCCESS WITH THE SELLING
PROCESS must be _studied out_. You should keep them always at hand like
your bank books, and draw on the contents for your salesmanship needs
from day to day.

You will get only a smattering of the secret of certain success if you
just skim over the chapters, and skip whatever requires you to think
hard in order to comprehend it all. But if you dig into the meaning of
each sentence for the full idea, you will enrich yourself with
constantly increasing power and skill in selling. _So you will surely
become a real success_.

[Sidenote: Tested Working Tools]

The principles and methods of successful salesmanship summarized in
these companion books, though they will be new to most readers, are not
mere personal theories. They all have been demonstrated and tested in
actual practice during my twelve years experience as Commercial and
General Sales Manager of the Ford Motor Company. Under my direction in
the course of that period Ford sales were multiplied one hundred
thirty-two times--from 6,181 to 815,912 cars a year. The fundamental
principles and methods that I have tested and proved to be most
successful in selling automobiles and good will should work equally well
in any profession, or business, or trade; and for any normal,
intelligent man or woman who uses them continually.

[Sidenote: Dollars and Cents Value]

Since the first publication of "The Selling Process" thousands of
enthusiastic readers of the book have voluntarily borne witness to its
practical, dollars-and-cents value to them in their daily work.
