The Master Key System
By Charles Haanel

Some men seem to attract success, power, wealth, attainment, with very little conscious effort; others conquer with great difficulty; still others fail altogether to reach their ambitions, desires and ideals. Why is this so: Why should some men realize their ambitions easily, others with difficulty, and still others not at all? The cause cannot be physical, else the most perfect men, physically, would be the most successful. The difference, therefore, must be mental - must be in the mind; hence mind must be the creative force, must constitute the sole difference between men. It is mind, therefore, which overcomes environment and every other obstacle in the path of men.

When the creative power of thought is fully understood, its effect will be seen to be marvelous. But such results cannot be secured without proper application, diligence, and concentration. The student will find that the laws governing in the mental and spiritual world are as fixed and infallible as in the material world. To secure the desired results, then, it is necessary to know the law and to comply with it. A proper compliance with the law will be found to produce the desired result with invariable exactitude. The student who learns that power comes from within, that he is weak only because he has depended on help from outside, and who unhesitatingly throws himself on his own thought, instantly rights himself, stands erect, assumes a dominant attitude, and works miracles.
