Ennui and Me

By all standards, I'm having a pretty kick ass day.  It was my late day to come in, so I slept a little late.  I slept pretty well last night after I tore myself away from Harry Potter (my book re-read in prep for the movie tomorrow).  I picked a ripe tomato off the plant this morning, which always makes me happy.  My parents took me out to lunch.  My dad bought and presented me with a new laptop at lunch (out of Chris money).  It's pretty sweet.  The weather is nice--less than 100 degrees for most of the day--and it looks like my lessons tonight will go smoothly.  And they're not even stressful lessons to teach.

And yet, I keep needing to encourage myself to keep my chin up and get back to work.  "just make it through today, and tomorrow will be better." 

What's with me?
