We may have a perfectly adequate way of doing something, but that does not mean there cannot be a better way. So we set out to find an alternative way. This is the basis of any improvement that is not fault correction or problem solving.
Edward de BonoThis new meta-system is very much in favor of the self, but a self that is based on a proper sense of dignity, not on an inflated ego. A person who dare not admit he is wrong inflates his ego but weakens his self.
