There's one thing I have to remember and keep in mind at all times: whenever I think about choosing between canceling one of my extras and going home for some rest, I shouldn't. There'll be no rest.
There'll be screams, shouts, unsaid things, frustration, suppressed desires, failed plans and headache.
Never ever cancel those classes. However unpleasant or boring they might be, that's the headache that pays. The home one doesn't.
