You could totally play piano. Anyone can, especially if you took even a few piano lessons. Portable keyboards come cheap, and you can get yourself a book and learn at your own pace. The key is making goals for yourself that keep you excited about practicing. For example, find a song that's simple and that you like, and work on that one. For me, it was Fur Elise. Keep an eye out for interesting pieces that will require more practice in the future like Chopin stuff (see: The Pianist) or even one of Tori Amos' two instrumental works (on the God maxi-single).
Coachella was so fun. but I'm running off very little sleep and being borderline dehydrated for two days, making it back to school to take a midterm has left me a little lacking in the energy department.
don't let this comment fool you, I'm actually asleep and typing this out with my face bashing the keyboard (I'm having a nightmare).
