pfh, don't forget simple masochism.
As for humour as a mode of thought: I wish I could be all dramatically "Woe is me!" depressed. Instead I find humour in all manner of things and laugh all too frequently. "How's it going?" I'm asked, and, "Absolutely miserably!" I smilingly respond. But that doesn't actually improve my mood or lift me far enough out of depression to do what I used to want to do, so . . . it's a bit depressing. (Ha!) I was a clown for a day - perhaps I should try to get paid to be one again.
Given the number of blogs wherein personal psychic problems are made public, I hope psychologists, psychiatrists, and sociologists are paying attention. That diaries, which used to be kept under lock, are now for public consumption is interesting in itself. I wonder how this is connected to the rash of "reality tv".
