I don't really have any of my own.
My middle son gets paid in various ways from video gaming, which he loves playing. He coaches, boosts, and plays competitively (now representing his university in e-sports).
My daughter is likely going to get a couple of music scholarships. According to the likely terms, she'll *have to* take lessons (but they're free) and will *have to* play in the orchestra and the band, which she wants to be in anyway.
