I don't manage when I stop, I manage when I *start*

Good thought -- I'll definitely try that.

But I wish I could manage when I stop -- not even to stop when I have something urgent to do, so much as to stop when I'm bored and not having fun any more. You wouldn't think that would be so difficult!

I know people who have chat on at work. I don't get that. I'd never get anything done at all.
