Cannot Concentrate

Today at work it is so hard to focus. I don't know what it is but I cannot seem to be able to wrap my head around working. Is it the weather? Is it because it's Friday? I have no idea, but I'm trying to do anything but my work. I may need to leave early today. I think I may take my lunch at 2pm and then flex the rest of my day. I think that is a fantastic idea!! I haven't left early in a very long time and I feel that I need a break :)
