I know it’s not the same, but sometimes when I am reading a really good book I keep wondering about what I am going to read afterwards, and then after that, and then after that. It actually stresses me out.
Recently I was reading Stephen King’s, It. I was really enjoying it. When I wasn’t reading it, I was thinking about it. And yet at the same time I kept concentrating on what I was going to read after I finished it.
Like you I need to enjoy being in the moment.
