Oh, I have an idea! Several, really. Why not read a book or manga based on something that you can't currently access otherwise (like a video game or show/movie that isn't on any of your current apps/DVDs)? The mangas were how my friend and I got into Kingdom Hearts (Along with Melodies of Memories ofc, but that one doesn't really count).
Or try out a fun band to listen to that you haven't before to add to your playlist! I strongly recommend Billy Talent (I recommend This Will get Better and This is How it Goes to get a summary of what type of music they play) and Incubus if you like songs that are along similar lines to songs like Radioactive (Imagine Dragons). Those bands make my day every single time!
You can also try out entering a contest of some sort. A contest was what sparked me into writing stories, maybe it'll give you a push into a new hobby!
Birdwatching can be good too. It can be relaxing to the soul and further your knowledge on birds if you write down the information in a journal. Not my personal preference, sure, but it's still nice.
