Eugen Sandow Mental Focus

If you hold your mind on some chosen object, you centralize your attention, just like the lens of the camera centralizes on a certain landscape. Therefore always hold your mind on what you are doing, no matter what it is. Keep a careful watch over yourself, for unless you do your improvement will be very
slow.

Practice inhaling long, deep breaths, not simply for the improvement of health, although that is no small matter, but also for the purpose of developing more power, more love, more life. All work assists in development.

You may think it foolish to try to develop concentration by taking muscular exercises, but you must not forget that the mind is associated with muscle and nerve. When you steady your nerves and muscles, you steady your mind, but let your nerves get out of order and your mind will become erratic and you will not possess the power of direction, which, in other words, is concentration. Therefore you understand how important exercises that steady the nerves and muscles are in developing concentration.
