And ask yourself, what problem have you solved, ever, that was worth solving where you knew all of the given information in advance; where you didn't have a surplus of information and you had to filter it out, or you didn't have sufficient information and had to go find some.
Perguntem a vocês próprios que problema alguma vez resolveram, que tenha valido a pena, onde tivessem todos os dados à priori; ou onde não tivessem informação a mais e a tivessem que filtrar, ou onde não tivessem informação suficiente e tivessem que descobrir alguma.
