I'm on vacation, so why am I trying to work?

What can I say of this past week? It had been only partially productive. I have revisited the first six Harry Potter films, was able to get some books for classes that I will teach next semester, exercised nearly every day, met with some friends, got to do some important stuff with regards to my visa which will expire in a month, and worked on a magazine I'm involved with, and some other stuff. I feel slightly frustrated though, as if I had not accomplished all I had hoped, but I cannot honestly say what it exactly is that I had hoped to accomplish. For this coming week I guess I better make a proper list of goals, so that I can check them off as the week progress.
