circulating or kinetic energy. His work glows with living fire.

Yet, for every such man there are a multitude of others, equally
gifted in some respect, but wanting that mysterious "Open Sesame"
which would discover their hidden mental riches, arouse them from
their accustomed inferiority to their best selves, and transform
potentiality into accomplishment. So it comes about that most of us
are gems that shine but to illumine the "dark unfathomed caves of
ocean," flowers born to "blush unseen."

[Sidenote: _Mental Effect of City Life_]

Take an illustration of the way in which this reserve or potential
energy is transformed into circulating or kinetic energy. Suppose that
you are a countryman and come to live in a large city. The speed with
which we do things, our habits of quick decision, the whirlwind of
activities of the busy man in town, appal you. You cannot see how we
live through it. A day in the business district fills you with terror.
The tumult and danger make it seem "like a permanent earthquake."

But settle down to work here. And in a year you will have "caught the
pulse beat," you will "vibrate to the city's rhythm," and if you only
"make good" in your work, you will enjoy the strain and hurry, you
will keep pace with the best of us, and you will get more out of
yourself in a day in the city than you ever did in a week on the farm.

_This change in degree of mental activity does not necessarily mean
that you are making more of a success of life._

Your activities may be ill-directed. Your new-found powers may be
misspent and dissipated.

But you are mentally more alert Your mental forces have been
stimulated by the stirring environment.

And, mark this particularly, _a number of mental pictures will pass
across the screen of your consciousness today in the same time that
one mental image formerly required._

_Now, you have learned that with every idea catalogued in memory,
there is wrapped up and stowed away an associated "feeling tone" and
an associated impulse to some particular muscular action._

Assuming this, you must at once see that here is an explanation of
your new-found energy.

Your quickened step, your new-found decisiveness of action, your more
observant eye, your clear-cut speech instead of the former drawling
utterance, your livelier manner, your freshened enthusiasm and
enjoyment of life--all of these are but manifestations
