Decirlo no significa ser negativo, sino ser preciso. La clave consiste en que, una vez que haya chocado, en lugar de castigarse a sí mismo por ser un \"fracaso\", recuerde que en la vida no hay fracasos. Sólo hay resultados. Si no consiguió los resultados que deseaba, aprenda de esta experiencia, de modo que en el futuro disponga de referencias acerca de cómo tomar mejores decisiones.\nTONY ROBBINS.\n¡Que todos y todas tengan buenos juegos!",
