Isn't that just the same thing as liking to keep busy?

It does seem to be remarkably difficult to train oneself out of the 'what have I missed?' reflex - what you say reminds me of my 'Have I turned the cooker off?' problem..

The difference between this and liking to keep busy is that I feel pleased to have time to sit back and relax. I'm not annoyed that I have nothing to do; I'm annoyed that the "what next?" reflex keeps interrupting my attempts to relax :-)

That said, if I were busier then I suppose this particular irritation wouldn't bother me; but I'm not sure that's quite the same thing as liking it...

Some people can't stand to do nothing - I can't unless I'm actually asleep.
