Sírvete de lo aparente …
Sírvete de lo aparente como indicio de lo inaparente.
Sírvete de lo aparente como indicio de lo inaparente.
La retentiva es el sello de la capacidad.
Pobre del estudiante que no aventaje a su maestro.
Los que emplean mal su tiempo son los primeros en quejarse de su brevedad.
El leer sin pensar nos hace una mente desordenada. El pensar sin leer nos hace desequilibrados.
— Confucio
El optimista cree en los demás y el pesimista sólo cree en sí mismo.
