Concentration of the mind can only be developed by watching
yourself closely. All kinds of development commence with close
attention. You should regulate your every thought and feeling.
When you commence to watch yourself and your own acts and also
the acts of other people, you use the faculties of autonomy, and,
as you continue to do so, you improve your faculties, until in
time you can engineer your every thought, wish and plan. To be
able to focalize the mind on the object at hand in a conscious
manner leads to concentration. Only the trained mind can
focalize. To hold a thought before it until all the faculties
shall have had time to consider that thought is concentration.

The person that cannot direct his thoughts, wishes, plans,
resolutions and studies cannot possibly succeed to the fullest
extent. The person that is impulsive one moment and calm the next
has not the proper control over himself. He is not a master of
his mind, nor of his thoughts, feelings and wishes. Such a person
cannot be a success. When he becomes irritated, he irritates
others and spoils all chances of any concerned doing their best.
But the person that can direct his energies and hold them at work
in a concentrated manner controls his every work and act, and
thereby gains power to control others. He can make his every move
serve a useful end and every thought a noble purpose.

In this day the man that gets excited and irritable should be
looked upon as an undesirable person. The person of good breeding
now speaks with slowness and deliberation. He is cultivating more
