I had an interesting experience last night.
The last few weeks I have found it very hard to be effective at work. I have for example a bit of marking that might take an hour. I think I should do it at the start of the day. At about 11pm I do it for an hour until midnight. Which is ok, except that I have done nothing else all day, or just maybe meetings, because the next thing to do is the marking and instead I facebook or find any other displacement activity. So I've not relaxed all day, and worried, and not done anything.
The last couple of days I've taken a workaround, of not worrying and not trying to do the small thing until late. Not ideal in many ways but better than before.
But the really interesting thing was last night. I went to order some things online for Christmas presents. It just seemed ridiculously hard. There was something which I could no longer get, so there was a minor difficulty. But it just all seemed so hard.
So it seems like I have been having a tougher time all round than I expected.
At least it's a good time for a holiday to be rolling round.
