I find I have no energy this evening.  I just want to sit here, and do nothing that requires a lot of effort.  Unfortunately, I have to finish this assignment the next two hours.  And I'm not all that pleased with how it's going thus far.  But that doesn't matter all that much in the end.  As long as it's done, it'll be fine, as it's a rough draft.  But I have quite a bit of other work I need to get done in the next three days.  Oh well.

Reading this over it sounds like I'm in a bad mood.  I'm not.  I'm in a tired, happy mood right now, which is better than how I was all day.  It's just not conducive to getting work done.
