Ah, to travel when you're young. Discovering new cultures and experiencing completely new things, it broadens the mind, so the official cliché goes. I think we've all heard or read examples of people who've been abroad - usually Asia or somewhere else poor, far away, and totally different from home - coming back talking about this new respect for life, this new disregard for materialism (at least for a while), and so on.
I'm not mocking this at all. I think it's wonderful for people to get fresh ideas from traveling, whatever they are. I myself however, I didn't visit any poor nations during my year abroad. I went to Australia, which apart from some obvious contrasts like climate, wildlife and language, is not that different to where I'm from. And yet, I wouldn't hesitate to admit that the year I spent Down Under has taught me more than anything else I've ever done.
