I don't know what it is, really. It could be the fact that it is Thursday. Or the seemingly fast approaching holiday. Or the wandering thought of positive life changes and a move. Or a strong cup of coffee in the morning. Or the sense of accomplishment that is imminent with one last push of work effort. Or the anticipation of a shopping trip with my mother as excuse for lunch break.
There are so many factors that influence our feelings (and subsequently, our actions and behaviors), that it is difficult to say what really "makes us tick" on a day-to-day basis. All I know is that today, I am feeling quite productive and energetic, hard to believe when all I have to give are the fumes of a week burnt at both ends. But it is the hope that counts, and feeling that some days are more exciting than others.
