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 was so emotional. Choked up. I could hardly talk all day. I'll be cleaning out my trailer and saying goodbye soon realizing what a wonderful experience this has been.
