One of my character flaws that seems to have become worse over time is that I can get absolutely obsessive about something that doesn't work. Yesterday and today it's about something technical (an "upgrade" seems to have broken the music functionality of my TiVo), but it can just as easily be about an idea (like last week's work frustration) or a relationship (don't get me started...).
I dream of my past failures and frauds almost every night. I don't sleep well.
So I'm in an awful mood and might be built to stay that way. And it's never about what it seems to be about. Besides which, I know that even many of the things that trouble me more deeply aren't things I should let myself be so bothered with.
