At the very end of a book I can manage to work for longer stretches but mostly making stuff up for three hours that's enough. I can't do any more. At the end of the day I might tinker with my morning's work and maybe write some again. But I think three hours is fine.
I start thinking about life after death. I've got to quit thinking about it because it's very deep. Very deep. Sometimes you start thinking about it and you don't feel like you want to be alive so I don't like to get all quiet.
