Uno de los primeros bestsellers de autoayuda publicados. Editado por primera vez en 1936, se han vendido cerca de 15 millones de ejemplares en todo el mundo. Este es un libro clsico acerca de las relaciones humanas, donde Carnegie profundiza sobre toda la psicologa que se pone en juego al momento de relacionarnos con otras personas, un valor fundamental tanto en la vida profesional como en la personal. Este libro se ha ganado a millones de lectores pues expone algo fundamental: es posible cambiar el comportamiento de los dems si cambiamos nuestra actitud hacia ellos. Por eso se trata de un libro que es ampliamente difundido en los sectores de ventas, marketing y liderazgo.
