Choosing a Language

I've wanted to learn a foreign language for quite some time now, and I'm having trouble coming to a decision on which to learn.

I've narrowed my choices down to Norwegian, Russian and Japanese.

My main problem in deciding  is that I feel like once I start, if I get any significant way through then I won't really be able to change my mind (without throwing away a ton of work which I would be unlikely to do). Norwegian also seemingly has a lack of good resources; it was what I was leaning more towards due to it's relative ease which would mean if I wanted to learn a different language later, I'd be more likely to try and get fluent in Norwegian first and then move on to a different language.

Any thoughts on the matter, /lang/? Thanks in advance for any replies.

I'm by no means an expert but I have in my life attempted to learn French, Italian, German, and Japanese, in that order. From the very start, I wanted to learn Japanese, but it looked hard as fuck, and I didn't want to, Hell I don't even know, I guess I was just intimidated; french went horribly and almost put me off languages, but I started learning Italian with a girlfriend for about 4/5 months, but we broke up and it was then it became obvious that I never really cared THAT much about Italian, so I started German but after one month I gave up because it was just plain obvious that I wanted to learn Japanese. Now I'm eight months in, feeling pretty good about the language, studying everyday and feel absolutely zero burn out.

tl;dr being, if there is one amongst them that you want to learn more than others, this anon at least thinks that one criterion  outweighs all the others.
