I only had one year in high school. Started learning because of how common it is in NASA / Роскосмос liaison operations (I’m going into space systems engineering, and all crew on ISS must be bilingual in Russian + English). But then cooperation and diplomacy fell apart so now we won’t have a joint orbital project soon. It’s sad to see it go but the hardware is getting old.

Ended up switching languages to learn Old Norse (I’m more into ancient languages), but I still pick up a few phrases in Russian every once in a while.
