I’m married to a Mexican but I enjoyed learning Spanish in school (in the Midwest); later in life after moving to Los Angeles I started using Spanish quite a bit.
If I can nudge you to try learning it, you might end up enjoying it. I’m crazy busy with work too but I’ve started learning Mandarin online with a tutor and after a bit of a learning curve, it’s deeply satisfying when things start to click.
In high school while studying Katakana one of the coolest things was having a dream of walking around Tokyo and reading the Katakana everywhere.
