At level 24, I ask people to consider hooking up with each other. To what extent are they using social media? Why not use that to build another language? They could even use two non-English languages at once so as to improve in more than one.
I watched a sumo documentary in Japanese about the Bulgarian, Kotooshu. That had me considering learning some Bulgarian in the future. And even some Mongolian so as to be able to approach wrestlers from that country.
You need a reason to learn another language. You also need to feel that it’s no great hurdle.
