When I was in late primary/early high school, I happened to be at a school with a lot of Norwegian expats. It was a very common joke among them that Norwegians are born with skis on their feet.

Norway did exceptionally well this year even by those standards, but yeah, it's hardly surprising that they do unexpectedly well at the Winter Games.

That said, this video is really interesting discussion on the topic. It's mainly talking about problems with American society, but Norway is particularly used as a comparison for just how to do it right in a number of ways.
