La acción es la verdadera medida de la inteligencia.
– Napoleon Hill

Whatever the mind of man can conceive and believe, it can achieve. Thoughts are things! And powerful things at that, when mixed with definiteness of purpose, and burning desire, can be translated into riches. Use auto-suggestion, have faith, imagination and overcome fear and time is your opposite player as in checkerboard.
– As quoted in Self-Motivation Through Risk Taking! Are You Leading Or Do You Wither with Problems? (2005), by M. Nadarajan Munisamy
