Power of Concentration

Quotation:
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.

I hv been buying/ selling based on impulse.. and that only gives me lots of activities with very very very little profit to show for - what worst, losses - more likely.
On the 4Hr chart, the sma34 crosses ema 200. Such crosses happen so long ago,.. I need to see what is the consequence. The cross is a bearish cross.
Closed my gold position at a loss. Now cash balance down to 294. I will hv to wait for the precise buy/sell moment and not jump in and out based on whatever I fancy, so help me Lord !
