Unfortunately, there is no legal protection against those who, either by design or ignorance, poison the minds of others by negative suggestion. This form of destruction should be punishable by heavy legal penalties, because it may and often does destroy one's chances of acquiring material things which are protected by law. p. 173

Building alibis with which to explain away failure is a national pastime. The habit is as old as the human race, and is fatal to success! Why do people cling to their pet alibis?

Through the combination of energy and matter, has been created everything perceptible to man, from the largest star which floats in the heavens, down to, and including man, himself. p. 64

Mind control is the result of self-discipline and habit. You either control your mind or it controls you. There is no half-way compromise. The most practical of all methods for controlling the mind is the habit of keeping it busy with a definite purpose, backed by a definite plan...Without this control, success is not possible. p. 173

Most people are too indifferent or lazy to acquire facts with which to think accurately. They prefer to act on "opinions" created by guesswork or snap-judgments. p.88
