Maybe it's all the driving I've been doing, or the way my schedule seems to demand the greatest concentration early in the morning and late at night, but I've been having a hard time maintaining a steady pace through my days. Sometimes I'm overwhelmed with a desire to sleep so strong that it's all I can do to keep my eyes open. But then just a few minutes later I get another burst of energy as I get excited about all the projects I have going. It's complicated, this relationship I have with my will, as they say on Facebook. Earlier tonight, after I'd brought Skylar home from her last night of basketball practice, I could visualize getting vast amounts of work done before morning. And then, after I finally put some food in my stomach, I just wanted to curl up with a book. Now I'm torn between the conviction that I better get out on my bicycle for a late-night ride soon -- it has been weeks since I mustered the motivation to hurl myself into the darkness -- and the nagging sense that what I really need is the sleep I've been deprived of during this challenging semester.
