It's my understanding that the language you speaks has only a small effect on your outlook. The gist behind the Sapir Whorf hypothesis was that the number of concepts you could grasp was limited by the language you spoke. But I don't think most linguists seriously believe this anymore. Research has shown language to influence our outlooks in limited ways, and even those findings are suspect, since some of the differences can be explained by cultural differences.
