Words Have Power – Napoleon Hill
"The subconscious mind makes no distinction between constructive and destructive thought impulses. It works with the material we feed it, through our thought impulses. The subconscious mind will translate into reality a thought driven by fear, just as readily as it will translate into reality a thought driven by courage or faith."
"Opportunity wastes no effort looking for the person who is wasting time through idleness or destructive action."
"Controlled Attention leads to mastery in any type of human endeavor, because it enables one to focus the powers of his mind upon the attainment of a definite objective and to keep it so directed at will. Great achievements come from minds that are at peace with themselves. Peace within one’s mind is not a matter of luck, but is a priceless possession, which can be attained only by Self-Discipline based upon Controlled Attention. Concentration on one’s major purpose projects a clear picture of that purpose upon the conscious mind and holds it there until it is taken over by the subconscious mind and acted upon."
