"He who knows all the answers
has not been asked all the questions"

Confucius
 

"Para ser grande, sê inteiro: nada          
Teu exagera ou exclui.                          
Sê todo em cada coisa. Põe quanto és
No mínimo que fazes.                           
Assim em cada lago a lua toda             
   
  Brilha, porque alta vive"                         
 - Antologia de Ricardo Reis -
Fernando Pessoa

“Imagination is more important than knowledge.
For knowledge
is limited to all we now know and
understand, while imagination embraces the entire
world, and all there ever will be to know and understand.”
A. Einstein
