Feeling Good...

It's midnight. I ate utter garbage today. I exercised halfheartedly, not working very hard. I overslept and missed a class. It was hot out. A couple of friends called me out on some stuff, I felt ashamed. Today was NOT an ideal day... so why do I feel good? Where is this feeling of motivation coming from? The only positive thing I can think of is that I am one step ahead on homework. Is that really all it takes to feel this motivation, to stay ahead of the wave of work? Or is this one of those stupid insomnia-filled nights and I only feel good because I ought to be sleeping? Will this feeling last until tomorrow? How can I make this feeling happen again? The amount of things I could get done with this feeling... Why didn't I feel it earlier in the quarter when I was also feeling the determination to do well? So many questions... No, just one: Why do I feel good?
