fritter it away in unprofitable
activities.

[Sidenote: _The Successful Promoter_]

To correct this is to gain mastery and power.

Concentrate your mental energies on one thing at a time. Stop
spreading them around. The promoter may have a dozen big enterprises
under way at once, but he takes them up one at a time. He transfers
his whole mind and thought from one to the next. You cannot of course
be eternally doing the same thing; but make no mistake about it, the
only way to succeed at anything is to consciously control your mental
energies. You may throw them now into this attack, now into another;
but you must always have a tight grip on yourself, or you cannot
succeed.

[Sidenote: _The Human Dynamo_]

You will often hear some "live-wire" business man spoken of as a
"human dynamo." He has the faculty of turning out a stupendous amount
of work in a comparatively short time. How he can carry in his mind
the details of so many large projects, how he can accomplish so much
in actual, tangible results in many directions, how he can pull the
strings of so many enterprises without getting lost in the maze of
detail, is the marvel of his associates. And yet this man is never
"hurried, nor flurried, nor worried." But every word and every act is
straight to the point and productive of results worth while.

[Sidenote: _Cool Brains and Hot Boxes_]

"A cool brain is the reverse of a hot box. It carries the business of
the day along with a steady drive, and is invariably the mark of the
big man. The man who dispatches his work quietly, promptly and
efficiently, with no trace of fuss and flurry, is a big man. It is not
the hurrying, clattering and chattering individual who turns off the
most work. He may imagine he is getting over a lot of track, but he
wastes far more than the necessary amount of steam in doing it. The
fable of the hare and the tortoise would not be a bad primer for a
number of us, and the lesson relearned would not only be beneficial in
a business-producing way, but it would help us in the full enjoyment
of our work."

[Sidenote: _Marvelous Increased Efficiency Handling "Pig"_]

Progress in mental efficiency must result from the application of
knowledge of the mental machine. Just as we watch the steam-engine and
the electric motor to see that they are not "overloaded," so we must
watch the mental machine, that no more power be turned on than can be
profitably employed.

This principle has already b
