m into channels that are worth while.

You are losing power in a turmoil of inward mental strains and
inharmonies. Catch yourself at some moment when you are forging ahead
in a crowded day's work. You will then see what an inner whirlwind of
excitement is in progress, what stresses and strains are at work, what
contrary impulses, what frictions and obstacles are being overcome.

Now, to the engineer every one of these words--friction, obstacle,
strain--spells loss of efficiency, and in this _Course_ we shall teach
you how you may do away with antagonistic impulses, may bring your
combined mental forces to bear upon the common enemy, and may hurl
yourself into the struggles of business and practical life with a
joyful and headlong impetuosity that no obstacle can withstand.

Professor Walter Dill Scott, of Northwestern University, has said: "In
studying the lives of contemporary business men, two facts stand out
pre-eminently. The first is that their labors have brought about
results that to most of us would have seemed impossible. Such men
appear as giants in comparison with whom ordinary men sink to the size
of pygmies. The second fact, which a study of successful business men
(or any class of successful men) reveals, is that they never seem

"Such men have time to devote to objects in no way connected with
their business. It cannot be regarded as accidental that this
characteristic of mind is found so commonly among successful men
during the years of their most fruitful labor. According to the
American ideal, the man who is sure to succeed is the one who is
continuously 'keyed up to concert pitch'--who is ever alert and is
always giving attention to his business or profession."

And again: "It is not necessarily true that the greatest and most
constant display of energy accompanies the greatest presence of
energy. The tug-boat on the river is constantly blowing off steam and
making a tremendous display of energy, while the ocean liner proceeds
on its way without noise and without commotion. The man who frets and
fumes, who is nervous and excited, is strung up to such a pitch that
energy is being dissipated in all directions."

Many business men know they are going at a pace that kills, and at the
same time they feel that they are accomplishing too little. For such
the pertinent question is, How may I reduce the expenditure of energy
without re
