Moving away to Europe- which Scandinavian country should I choose?

I won a substantial amount of money in a lottery jackpot about a year ago, and I'm finally ready to leave the U.S. and move to Europe, now that I've taken care of all the legal and financial shenanigans that come along with sudden, unexpected "wealth". I have always been fascinated with the north, and am contemplating a move to either Norway, Sweden, or Finland. Actually, I'm leaning towards Norway or Sweden, since their languages are quite similar and the learning curve wouldn't be so steep for me as opposed to having to learn Finnish (yikes!). I took great care to invest all of my winnings very wisely (and steer clear of the markets here in the U.S.), diversified throughout the entire world, so I won't ever be dependent on my new country's welfare system in any shape, form, or fashion. I also want to continue teaching physics, math, and German in my future country as I've been doing all along, so my question is....which Scandinavian country would be best for an "immigrant" in my situation? What type of additional preparation will I have to complete in order to be able to teach in Norway or Sweden? One of the main reasons I'd like to move there (aside from being absolutely comfortable in cold weather) is because of the improved quality of life I believe I would have as a black person there. I'd like to hear from anyone who lives in Sweden or Norway, or who may have moved there or at least spent a couple of years there as a foreigner. Thanks!
