though not concentrating. Those that are in a negative state a
good deal of the time cannot, as a rule, concentrate very well;
they develop instead abstraction of the mind, or absence of mind.
Their power of concentration becomes weaker and they find it
difficult to concentrate on anything. They very often injure the
brain, if they keep up this state. To be able to concentrate you
must possess strength of mind. The person that is feeble-minded
cannot concentrate his mind, because of lack of will. The mind
that cannot center itself on a special subject, or thought, is
weak; also the mind that cannot draw itself from a subject or
thought is weak. But the person that can center his mind on any
problem, no matter what it is, and remove any unharmonious
impressions has strength of mind. Concentration, first, last and
all the time, means strength of mind.

Through concentration a person is able to collect and hold his
mental and physical energies at work. A concentrated mind pays
attention to thoughts, words, acts and plans. The person who
allows his mind to roam at will will never accomplish a great
deal in the world. He wastes his energies. If you work, think,
talk and act aimlessly, and allow your brain to wander from your
subject to foreign fields, you will not be able to concentrate.
You concentrate at the moment when you say, "I want to, I can, I
will."

Some Mistakes Some People Make. If you waste your time reading
sensational stories or worthless newspaper items, you excite the
impulsive and the emotional faculties, and this means you are
weakening your power of concentration. You will not be a free
engineer, able to pilot yourself to success.
