You have been endowed with the power to use the most highly organized form of energy known to man, that of thought. - Napoleon Hill

Every person who wins in any undertaking must be willing to burn his ships and cut all sources of retreat.

Make it a rule of your life to use your Tongue for high purposes alone. Resolve to speak in no way of any man or woman unless you can speak of the good qualities of that man or woman. No one ever gained Happiness out of injuring the Feelings or Character of someone else. No one ever failed to get Happiness by speaking well of other people.

Your subconscious mind recognizes and acts only upon thoughts which have been well-mixed with emotion or feeling.
