Can't focus...

I've been at work since 10 this morning and have gotten absolutely nothing done as far as my homework is concerned. Nothing seems important to me right now except getting out of work and going home. That's probably not a feeling that I should be having right now, and maybe it's being brought on by the long weekend that I have ahead (because I don't have any class/work on Fridays and we have Monday off for MLK day), but I just can't seem to care.
