One of my favorite videos on approach to programming, the notion that there is no silver bullet to programming and there will never be one perfect language for all your needs is the mantra a polyglot lives by. For me a polyglot is an open minded infidel who sees his world beyond hate and security, he is someone who understands that perfection is not achieved by ant like dedication. He bend his tools for the purpose and not the other way round.
