I had a dream just a few nights ago in which I was pulling a complicated baggage cart across a park. The details were not quite clear. As is typical in my dreams, the place seemed to be both Central Park in New York and a park in Boston and my destination was both downtown New York and a university in Boston. I was pushing and pulling at this load, and even in my dream it clearly appeared to have something to do with my work finishing up this book. It was tough going, but I looked around and found that I was in a whole group of people, friends and associates, who were walking along with me on this expedition. It felt good to know that I was part of a group, that I had a whole bunch of people with me, even though I seemed to be the one doing the pushing and pulling.
