Heredity counts for something. We are born with subconscious mental tendencies; as, for instance, a tendency to melancholy, or cowardice, or to ill temper; but all these subconscious tendencies may be overcome. When the real man awakens and comes forth he can throw them off very easily. Nothing of this kind need keep you down; if you have inherited undesirable mental tendencies, you can eliminate them and put desirable tendencies in their places. An inherited mental trait is a habit of thought of your father or mother impressed upon your subconscious mind; you can substitute the opposite impression by forming the opposite habit of thought. You can substitute a habit of cheerfulness for a tendency to despondency; you can overcome cowardice or ill temper.
It has been found that a small brain section, with many fine and active cells, gives as powerful expression to faculty as a larger brain with coarser cells; and it has been found that by turning the Principle of Power into any section of the brain, with the will and purpose to develop a particular talent, the brain cells may be multiplied indefinitely.
Any faculty, power, or talent you possess, no matter how small or rudimentary, may be increased; you can multiply the brain cells in this particular area until it acts as powerfully as you wish. It is true that you can act most easily through those faculties that are now most largely developed; you can do, with the least effort, the things which “come naturally”; but it is also true that if you will make the necessary effort you can develop any talent. You can do what you desire to do and become what you want to be. When you fix upon some ideal and proceed as hereinafter directed, all the power of your being is turned into the faculties required in the realization of that ideal; more blood and nerve force go to the corresponding sections of the brain, and the cells are quickened, increased, and multiplied in number. The proper use of the mind of man will build a brain capable of doing what the mind wants to do.
The brain does not make the man; the man makes the brain. Your place in life is not fixed by heredity. Nor are you condemned to the lower levels by circumstances or lack of opportunity. The Principle of Power in man is sufficient for all the requirements of his soul. No possible combination of circumstances can keep him down, if he makes his personal attitude right and determines to rise. The power, which formed man and purposed him for growth, also controls the circumstances of society, industry, and government; and this power is never divided against itself. The power which is in you is in the things around you, and when you begin to move forward, the things will arrange themselves for your advantage
There is a Principle of Power in you; if you use it and apply it in a certain way you can overcome all heredity, and master all circumstances and conditions and become a great and powerful personality.
