Pain is weakness leaving the body...

Not. Pain is your body telling you that the muscle fibers, connective tissues, and nerves are under stress and want you to stop what you're doing.

I had a long day at school today. The first four hours aren't so bad because they're just classes and stuff, it's the five hours of rehearsals afterward that really mess you up. 5 hours on a 16 and 3/8" viola really does a number on your body. The muscles in my shoulders ache. The nerves in my elbow are giving off a very unsettling feeling. The tendons in my left wrist are aching.

Maybe my body will get used to it in a few days.
