¡Atrévete a pensar!
¡Atrévete a pensar!
El tiempo saca a luz todo lo que está oculto y encubre y esconde lo que ahora brilla con el más grande esplendor.
La esperanza es un estimulante vital muy superior a la suerte.
Saber escoger el tiempo es ahorrar tiempo.
Ser es hacer.
El propósito de la educación es cambiar una mente vacía por una abierta.
La ocasión hay que crearla, no esperar a que llegue.
Para las personas creyentes, Dios está al principio; para los científicos, al final de todas sus reflexiones.
