I think this goes further than a plate of food, I myself have trouble stopping anything I'm doing much less eating, for me even something hard has to be finished in a timely manner. For example the other day I was power washing my driveway and had to take my little boy to ball practice, instead of feeling happy I was getting a break, I had to make myself quit. Here I was doing something not even enjoyable and I had to make myself quit to go and do something that enjoy quite a lot. Of course the idea of finishing what you start is usually a good trait to have, but not so in this case. I also remember being bragged on as a child because I could eat so much, but my wife's family would call you a pig if they would have seen me eat that much. I'm not sure what matters the most, but I can guarantee you that it all matters some.
