I realized that I had become obsessed with the political process. And, it is in my nature to get obsessed with things. I am essentially what I call a "serial obsessive." By that I mean that I get obsessed with things, then get bored with them and move on. Politics, however, has been a little different.
In the case of politics, rather than getting bored, I found that the more I got into it, even before the election, the more depressed and angry I found myself getting. I realized that I was taking it all much too seriously. So, I decided before the election, regardless of who won, I was going to "retire" from active political analysis.
