As Nexusone is saying here, norwegians can be quite serious and won't talk to people they don't know. Anyway, most of norwegian people speaks english fluently, and because of that, I don't think you would have any problem being integrated to the norwegian society.

I would advice you to head to Oslo at first, maybe Bergen. Many coffee-houses and brand clothing shops actually do hire people from other countries, as long as they speak english. Get a job, go drink a few beers with your co-workers, make friends, and learn the language and norwegian culture from there.

At the same time, if you do have the capacity and resources to go to a norwegian course to learn the language and the culture - I would recommend you to do.


Anyway,
Norway is a fantastic country, so get here and follow your dreams!
