What motivates you to learn another language?

I studied Spanish for 2/4 years in high school I've learnt a decent amount of Russian on dulingo but every time im learning another language I just remember that I live in New Zealand it's almost never I hear something other than English. I'd love to learn Russian as I find it a beautiful language but at the same time I have no interest in going to Russia I've never even met a Russian.

How/why do you stay motivated to learn another language if you're realistically never really going to speak it?
