Late for Class Again

I'm only just starting to accept my submissive side, but even without acting on it yet, I still struggle with the rules and expectations. Last night, after a long day of studying, Master had given me a strict curfew before bed, he said no later than midnight. I ended up finishing one more chapter though, feeling like there was just enough time to squeeze in the extra work without consequences. But when my phone alarm woke me at six for classes, I realized it was already past nine from staying up too late. Another day, another reason to feel guilty about breaking a rule I set for myself.
