Attending a WASC conference near Irvine.  The talk was well received, but after the conference, I was surprised that my mood is low.  Drove around UC Irvine, saw the alma mater changed over the last 15 years.  Went to a Taiwanese restaurant call cafe 302, it is packed so I have to get a burger from the near by Carl's jr.  The burger is fine but I felt disappointed.  Try to find something interesting to do, found out I don't want to do anything but come back to the hotel room and study and work on emails.  Depressed.  The never ending emails frustrated me, yet I felt compelled to do it.  Maybe I should change my habit and limited my work to the working hours.
