When it all boils down

I thought I would be really happy to quit piano. I finally won't have to go home and resign myself to practicing for1.5 hours. However, when it all boils down to the last day before my exam, the feeling's actually kind of bittersweet. Yes, I'll finally be free, but this is something I've done for the past 11 years of my life. After all that, am I really willing to just give it up? Of course, I could just continue sporadically with lessons, but would they really be worth it if I'm so busy with school and, eventually, university? Also, how could I possibly motivate myself to the extent I'm at right now if I don't have the pressure of an oncoming exam to prepare for? Sigh.
