I'm Ready

It's happened. I'm ready for school to start again. I'm not bored yet, not stir crazy, but I just feel like I'm not accomplishing much, not getting the same level of intellectual nourishment that I get when I'm in the midst of a semester. I thought I would really enjoy my time off this winter, and I am. But I'm ready. And I still have two more weeks to go. I think I need a new short-term hobby - any suggestions?
