On earth there is nothing great but man;in the man there is nothing great but mind.
地球上唯一伟大的是人,人身上唯一伟大的是心灵。
The whole is different from the sum of its parts.
Cada libro es una puerta a un mundo desconocido, una invitación a explorar lo desconocido.
I don't let the past hold me back. I let it propel me forward.
