Idk. I feel like instead of searching Google for hobbies, she could spend time with people other than Maya and MC. Like Jill for instance, they're friends and Jill has her own interests—music, horseback riding, tennis, wine tasting, etc. Josy could tag along for one of those, see if she finds one she likes too and build on that. Or hang out with her HOT sisters, like Riona seems a little lonely outside of Cammy and her business with Quinn, no one wanted to go to the arcade with her
Josy shares her room with Heather, who very much wants to get to know her. Elena is cool, Cammy is sweet, Ashley is fine I guess, Josy likes Lily and Sage, (who also has some trouble finding hobbies) Arieth is... Arieth. The rest are bitchy but still, that's a lot of options to try and find a hobby.
