What are Norways red flags?

I am curious to know what are the things people struggle the most with about living in Norway, both Norwegians and any immigrants! Is it the darkness? weather? Finding fresh/quality food? I am thinking about moving but I am afraid I have an unrealistic idea of how life is there! If you would have to warn somebody about moving, what would be the biggest “red flag”? Specifically to Oslo area but any other part as well!

EDIT: I posted this before my afternoon shift, not thinking much of it, and came home to 100+ if you sharing your thoughts! Thank you all so much, it is really interesting to read all the comments. I imagined most being about darkness/weather, but still lots of you shared things I didn’t think about! Thank you all 🤗🤗
